Will iMac 27" Quad improve Aperture performance?
Hello:
I currently own a 24” iMac 3.06 core 2 duo with 4gb memory. Aperture is still slow, sometimes very slow, in making multiple adjustments.
I was thinking of upgrading to one of the new 27” quad core machines (i7 8gb ram). Is there any hope that this machine will run aperture noticeably better or will I be wasting my $?
Thanks,
Jeff Stulin
the benchmarks show the i7 to be up to 3x faster (geekbench) then your imac....but ps cs4 is only 10-20% faster....all software that fully utilized the i7 chip will fly on that machine....
the problem with the imacs is the storage bottleneck.....fw800 becomes a problem when you are working with a cpu and gpu that wants to and can push data around like the i7....so in theory, final cut would be amazing on this...but there is no way to get uncompressed video in or out!
great to have a superfast cpu to work with but files take forever to open up because there is no adequate way to transfer the data.....
i just got a SSD for my mbp and aperture flies all of a sudden.....the (referenced) library (all files on a external sata raid via expresscard slot) opens up instantly, adjustments are smooth...this is the biggest performance jump i have ever seen in a computer, and all i did was change the HD and add the sata....ps is not really faster (although open/save and scratch are much faster)...going to fw 800 feels like working on usb all of a sudden.....
the internal HDs in the new imacs have some kind of heat sensor, so swapping drives can't be done and it is really hard anyway....unlike a mbp, there is only one internal drive anyway (the optical cannot be swapped) and obviously sata is totally out.....
in short, as much as i **** for the new imacs and especially the i7, it just isn't a workhorse replacement.....and when the mbp comes with the i5 or i7 and cs5 can take advantage of the chips they will be the much better option....
you have a nice large screen and a fast cpu now.....aperture will be faster on a i7, but there are many other aspects to consider all of which involve data transfer and none of the imacs can improve your situation in that regard......

Hello,
I've got a G5 dual-core 2.0Ghz (PCI-e model) and I'd like to boost its performance. I'm considering two options, but can only afford one. I'd like some help deciding which would have the greatest effect for my needs.
Option 1: upgrade from 2.5GB to 4.5GB of RAM
Option 2: upgrade from 6600 to x1900 graphics card
I'm a fine art photographer, and I use Aperture and Photoshop daily. I do most of my editing in Photoshop, and basically use Aperture as an image management system. If I had to choose between improving Aperture performance, or improving Photoshop, I'd probably choose Photoshop. (Of course I'd prefer both!)
I understand that the x1900 will improve Aperture a lot, but will it affect Photoshop at all? Will it have any effect on the general GUI "responsiveness" and applications like Safari, iCal, etc.?
I'm guessing the 2 more gigs of RAM will help Photoshop, but how much? Will it be significantly noticeable? Will more RAM help Aperture noticeably?
Thanks for your help understanding the finer points of this.
Best,
ChrisThank you for your very thorough reply. I have a couple of questions comments (below).
Option 1: upgrade from 2.5GB to 4.5GB of RAM
I did go ahead and upgrade to 4.5GB of RAM. So far, any performance improvements that might have happened are barely noticeable. Actually, the app I notice the most change in is Aperture, which is nice.
The more you fill a boot drive (or any drive) over
50% the slower it will perform, since your are
caching/swapping memory to the boot drive constantly
due to insufficient RAM, this makes everything slow.
I'm using a "sandbox" set-up with a backup/cloning program called SuperDuper. I have a 74GB Raptor set as the sandbox, which means it has a copy of the applications and system installed on it but nothing else. Of 70GB available, 15GB are used - leaving roughly 80% of free space.
The internal HD (400GB, 7200 RPM) has my system and user files on it. That drive has 150GB used, so about 60% remains. It would seem disk space is not the problem, right?
You probably know how a sandbox works, but for those who don't... it enables me to install updates to the system and apps and test them for a while. If there aren't any problems, I use SuperDuper to "smart update" the HD with new changes. If there are problems, I simply boot back to the HD and then roll back the sandbox to the state it was in prior to the updates.
Finally, I back up that internal 400GB HD to an external 400GB FW drive.
I don't know what effect, if any, the sandbox configuration has on speed.
If you go through the steps of a backup/c boot from
the Tiger installer/disk utility erase with
zero/fresh install of Tiger/update/install apps and
update and all that for the boot drive, your machine
will perform better as well as this will optimize the
drive as well as eliminate any glitches that have
occurred which may be affecting your performance in
other programs.
I understand everything you've said here, except for "backup/c boot". What is that?
If you just run one major heavy duty program at a
time, it will have all the RAM for itself, instead of
sharing it. Supposedly 3.5 GB is what Photoshop CS2
could optimally use, then you need a 1GB for Mac OS
X. If you have Dashboard widgets up the kazoo that
eats memory. (reboot to clear)
I have five widgets active, and maybe 20 in the toolbar (do those use memory too?)
Use X-Bench to test your boot drive speed. Your
looking for the fastest 4k uncached write speed as
you can get.
I've never done this. Is it self-explanatory if I download x-bench?
Are you saying you have a RAID 0 with two 10,000 RPM drives? (Sorry, I know very little about storage tech). If so, with only two internal drives on the G5, where do your files go?
Thanks,
Chris -
Aperture performance on a PowerBook G4?
Wondering what type of performance I could expect from Aperture if I installed it on my PowerBook G4. The system is 1.5GHz with 1 GB. Graphics card is a ATI Mobility Radeon 9700. I'm running OS X 10.4.7.
I've seen posts (a recent one on iBook) where folks are having trouble the software.

iBook commentary does not apply to Powerbooks, especially more modern higher end ones like yours. There is a reason iBooks were so cheap.
My PB G4 is a small bit stronger than yours (1.67 GHz, 128 MB VRAM) and I have always described it as "adequate" to run Aperture. However, I never said it ran Aperture "well." For sure you would need to increase your RAM to at least 1.5 GB, preferably 2 GB.
I recently ordered a MBP, and improving Aperture performance was the sole reason for doing so.

Does aperture require a dedicated video card? If not a requirement? does it improve the performance of aperture?
Aperture can work with integrated video, but the consensus here is that Aperture is fairly demanding when it comes to graphics cards, as it relies on them for various processes. So, if you have the option to get a machine with a dedicated video chipset, do so.

27" iMac upgrade priorities for Aperture use?
I am about to pull the trigger on a new iMac 27". Current Aperture librabry is about 700GB and this is my primary computer use. Libraries currently live on a 1T Rugged drive and are shared between an 2009 21 iMac and 2010 13MBP. Things are just too slow and I want more screen space. Trying to sort out best use of funds...so, base config looks like this so far:
3.2GHz Quad-core Intel Core i5
16GB 1600MHz DDR3 SDRAM
1TB Fusion Drive
GTX 675MX 1GB GDDR5
In terms of more bang for the buck, does it make sense to upgrade to:
3.4 i7 ($200)
3T Fusion ($150)
680MX 2G ($150)
I currently have a 2T USB 3 external and a 3T Firewire external (Time Machine BU). I am thinking, given I need a mobile solution for traveling and working out of home, keeping the libraries on an external would negate the need to upgrade to a 3T fusion. My understadning of Thunderbolt and USB3 is I would not notice the difference working externally or on an internal Fusion-is this more or less correct? Better to spend the money on an external Thunderbolt when they come down a little more?
680MX is considered a fast gaming card...but might it also "future-proof" (if you can even do that these days!) the mac for graphics requirements to come? Or is it overkill for Aperture and PS? Again-better to spend the money elsewhere?
I am leaning towards the faster processor. Although I hear mixed things, the tests I have seen do say this will give an overall boost.
I would welcome any insights from others who walked this path...
many thanks
NJI might be missing something*, but if this is correct:
My understadning of Thunderbolt and USB3 is I would not notice the difference working externally or on an internal Fusion-is this more or less correct?
_and_ you need to access your Library from multiple machines in multiple locations, why not just stick with the base iMac configuration you posted and put your Library on your 2 TB USB-3 drive? As long as you are not putting the Library on the internal drive, I think your thinking here is correct:
I am thinking, given I need a mobile solution for traveling and working out of home, keeping the libraries on an external would negate the need to upgrade to a 3T fusion.
I run very large Libraries off external USB-3 drives (mounted to an rMBP w. 16 GB RAM and a 500 GB SSD) and find the performance is no different than when using a large Library that is stored on the SSD. (I have seen no reason to expect external Thunderbolt drives to be noticeably faster than USB-3.) I think the 3 TB Fusion makes sense in a laptop; for your stated needs, I wouldn't upgrade (you may have additional storage needs you didn't mention, though).
I agree with William about the faster GPU -- but just on a hunch. I think Apple's programmers have gotten expert at getting performance where they can, and one place they seem to look is the GPU. For Aperture users, I would say about the GPU the same thing one has always said about RAM: when you buy a new machine, put in as much as (or the fastest) you can afford. Once you have 16 GB of RAM I would spend some money on a GPU upgrade.

Dear members:
After some disappointments with the latest version of Bridge (CS3) I decided to start working with Aperture as I found it offered some interesting tools for viewing and selecting images.
First I worked on some test images and everything went well. However, last night I did my first import of "real world" images and experienced severe performance issues.
I imported one folder containing 163 photos to two different locations - the folder and the images were the same but imported into two separate locations in Aperture as I was trying to create the ideal file structure for me.
These are the questions and/or problems I have.
1. This IS NOT a major problem. As much as I tried to import photos into an album or folder I couldn't do it. I don't like the project concept and prefer to have my images placed into folders or albums. My iPhoto library was imported by Aperture using this structure. The iPhoto library is a folder with albums as subdivisions as they were set up in iPhoto originally. However, this doesn't seem to be working as I import photos from other locations.
Q: How can I import photos into folders or albums and completely avoid the projects concept and icons ?
2. This IS major problem. Performance was very poor. I imported the folders last night and waited for approximately 30 min until I decided to turn my computer off. Aperture gave me a message stating that it was still generating previews and asking me if I wanted to quit. I pressed the OK button and turned the computer off. This morning I launced Aperture again and it went back to the spinning wheel on both projects. It must have taken approximately 45 min until the spinning wheels were no longer turning.
This is a problem for me as I have a library with approximately 15,000 - 20,000 images. The ones I imported last night were CR2 generated by a Canon 1Ds MK II (17 MB each). I can only imagine how long it would have taken had I chosen to import the 120+ MB TIFF images I also have in my library from slide scans.
My Aperture preferences have been set for Preview Quality = 12 and Limit Preview Size = Don't Limit. I have it set this way as I don't with to have reduced size previews so that (1) they can display with the highest possible quality as I mostly use the full screen mode for viewing and selecting images, and (2) in case I upgrade to a larger monitor in the near future (I have a 23" cinema display but am planning to upgrade to a 30") the previews will still work with that monitor.
Is this performace typical of Aperture ? I understand my camera is a professional camera that generates large images but isn't Aperture supposed to be a professional application aimed at professional photographers ? And what about those who work with 39 MB images from a Hasselblad or with scanned 120+ MB slide images ?
Is there something obvious I have forgotten to look at or set up in Aperture ?
Thank you in advance,
Joseph ChamberlainSteve:
Thank you very much for your reply to my post and for your suggestions. Some comments about my experience appear below. I am grateful for your help and don't wish in any way to discuss what you recommend below. I just wish to share my view of this issue and also to try to find the best answers for my problem.
For 1, use File > Import > Folders Into A Project. That will retain your folder
structure using brown folders and albums.
See:
http://www.bagelturf.com/aparticles/library/fivesimple/index.html and
http://www.bagelturf.com/aparticles/library/brown/index.html and
http://www.bagelturf.com/aparticles/library/libinadv/index.html
A. You can't. Projects are the container for everything in Aperture. No
projects, no images. So just live with them and subnvert them any way you
like. I don't have "projects" so I just use months, vacations, events, or
whatever keeps my image collections a reasonable size.
As an user I would like to have control over my own filing structure. This works quite well in iPhoto and I don't understand why Aperture chose to adopt this less flexible file structure. Also I noticed that the imported iPhoto library appears in Aperture inside a folder with multiple albums. Since Aperture can do this for iPhoto I find it hard to understand why it can't do for other imported images.
2. Turn off previews and delete the ones you have. When you find you need > them, use them selectively:
http://www.bagelturf.com/aparticles/previews/pwho/index.html
As stated in my previous post I always (no exception) use the full screen mode for viewing my images which is similar to a slide show. So according to the web page you reference above I would fall under the category of users that need previews.
You don't need high res previews. Aperture already generates thumbnails
for you.
General speed tips:
* Get the best video card with the most RAM you can afford
I can't. My computer is fairly new as it was purchased a little more than 2 years ago. Although it is a fairly new computer Apple no longer offers parts for it. My video card is an ATI Radeon 9600 Pro with 64 MB of VRAM installed. I have contacted Apple about this issue and they tell me there is nothing they can do. I have also contacted both ATI Radeon and nVidia and both have discontinued the only two cards they would work in my system (X800 XT Mac Edition and GeForce 6800, respectively).
* Smaller screens are faster than larger screens
My screen is 23" which I would consider to be a medium size screen by today's standards. However, isn't the purpose of working with Aperture to be able to develop a professional workflow ? And don't most professionals like to use large screens to view their work ?
* Avoid H&S adjustments until all the others are done
* Make sure you have sufficient RAM (2G minimum, 3G on a Mac Pro)
My system has 2.5 GB RAM installed. It has been suggested to me that I should add another 1 or 2 GB RAM as it would improve performance significantly. I have no problem doing that and would welcome that solution if I knew for a fact it was going to address my issues. However, I have already invested too much on hardware and software while still finding myself struggling with the issues I have described. Do you think the additional RAM would solve the problem ?
* Don't use previews unless you need them
Based on what I have read on the pages you referenced it seems to me I am one of those users who needs previews.
* Keep projects small. Use blue folders to group projects
My current filing structure is simple - I four folders each with subfolders containing in average 200 to 1000 images each. Some have as little as 1 image and some have 1000. But the majority would fall in the 300 to 400 images range.
* Rebuild the database once in a while
* Quit other apps if memory is restrictive
It seems in this case that the RAM upgrade I mention above would be helpful. Would it allow me to run other applications while also running Aperture without any noticeable performance alteration ?
To a great extent you have to rethink your workflow once you use Aperture.
Many people do a lot of unnecessary things because they are coming from
an environment that forced them to. Start from scratch and ask yourself
why you do everything you do. Much of the effort you will find is wasted
because Aperture either does it for you or make it unnecessary.
I am trying to simply my workflow as much as I can but not at the expense of quality. Bridge CS2 did a very good job for me. In many ways it was the perfect application althout it didn't have many of the great features I find in Aperture for reviewing and selecting images. First it was simple - all you had to do was to create your own file structure and then point Bridge to the folders as it would create its own previews. Second it was fast - this process happened a lot faster compared to Aperture and Bridge CS3. Third it was high quality - the previews generated were high quality and could be seen with amazing resolution while in slide show viewing mode on my 23" screen. My upgrade to Bridge CS3 was disastrous as (1) it has many bugs Adobe hasn't taken the time to fix, (2) it is slow on average machines requiring the latest hardware to run efficiently which is unrealistic for most consumers and (3) the previews generated are soft and appear pixilated and in poor quality while in slide show view.
I am going back to Aperture after a very disappointing start as I was one of the very first to purchase the software as soon as it was introduced only to be frustrated with all of its bugs and design flaws. Aperture has one of the best interfaces I have seen on any imaging application and I would really like to use but after this new attempt to use and the barriers I have encountered I am not sure I can.

Aperture performance on MBP 17" 2.16GHz Core Duo
Hi everyone,
I've been happily using Aperture for a couple of years and apart from a few niggles I love it.
I'm using a Macbook Pro 17" 2.16GHz (Core Duo) with 2GB RAM (the maximum) and an after-market 320GB 4200rpm internal hard drive. Running OS X 10.5.8 and Aperture 2.1.4. My hard drive is quite full, about 25GB free space. My Aperture library is about 60GB.
However I recently upgraded from a 6MP dslr to a 15Mp dslr and at approximately the same time Aperture performance began to take a nosedive. Now opening an image will sometimes beachball for 10 seconds (at other times they open normally in about 2 seconds). Cloning has become a nightmare of sluggishness, just clicking the retouch tool will beachball for 10 or more seconds and every edit will take a few seconds to appear.
Apart from buying a new Mac, what are my best options to improve performance? Its got so bad I'm starting to think about switching to Lightroom! (I read somewhere that Aperture is limited by the video card RAM, and my card only has 256MB I think. Apparently Lightroom doesn't do this?)
Thanks!
Edit: Don't know if it has any relevance, but I have never used Aperture's Vault feature. I don't even really understand it to be honest . I backup my photos online to Mozy.
Message was edited by: Timothy HoughtonThe file sizes on the 15 MP files are 2.5x larger than on the 6 MP camera. So by nature it's going to be slower.
What's causing it? Probably a mix of all 3. That machine is 2.5 years old now; things have gotten faster and with larger RAW file sizes it will be taxed.
You could always see if you could get to an Apple Store and load up a card with a few of your images and see how it goes. Challenge being, new machines are running 10.6 and there have been reports here that Aperture on 10.6 is slower than it is on 10.5 (seems better with 10.6.2 than 10.6.1 but still not sure if it's 100% as fast) so there are a lot of variables going on there. -
Maximizing Aperture Performance
I'm on the trial right now, but definitely plan on buying the software. I'm an amateur shooter, and I like the RAW processing and overall flow of the software.
I have an Intel iMac with the x1600 graphics card and 1.5 GB of ram. As I've added more files to the library (and I'm still under 1,000) I'm seeing it start to slow down a bit. Nothing that scares me, but I'd like ideas on how to best maximize performance. I have the library on my internal HDD. Should I use multiple libraries and really restrict their size? Keep the libraries off line? Use referenced images, kept on my external firewire drive? Anything else? I've turned previews off. Should I get that extra half GB of ram (max is 2 GB)?
I really like the software, and want it to remain a pleasue to work with. And I'm definitely not in the market for a new computer.
Thanks.The hard drive on the computer is well above 50%
full.
How full? There are no firm rules, but above 70% can
be crippling, above 85% destructive.
The hard drive is 65% full. Sounds like I need to clean it up.
Will Aperture performance suffer if I move the
library to my firewire drive, or should I offload
other files to the external drive?
Please describe all the mass storage. E.g. FW 400 or
FW 800? What size(s) and how full? etc.
The external drive is FW 800. 500 GB, pretty much empty right now.
What about using referenced files or multiple
libraries? If I'm working with perhaps 10,000 or
20,000 pictures (down the road) should I worry
about
breaking them up into multiple libraries?
There are many pros/cons (see previous threads) and
version 2.0 may provide new guidance/choices.
Personally IMO Referenced images seem to be a
necessity for laptop users. Desktop users have the
option of huge RAID libraries.
I don't have the RAID option, but I do have the FW drive. Should I go that route (libraries on the FW drive), but not referenced images?
Half a GB of additional ram is worth it, huh?
IMO yes, but it comes down to your individual
financial decision. I have always recommended against
iMacs for Aperture due to RAM limitations.
I guess for me the issue is not one of selecting an iMac for Aperture, but rather the approach to maximize the performance now that I've chosen Aperture for my iMac.
Thanks.

Value of upgraded RAM in imac 27" quad core
Friends,
I have a 27" imac i7 quad core on order. I do a fair amount of editing in FCE and Aperture. Does anyone have any sense of whether there would be a noticeable difference in processing speed if I upgrade the RAM to 12gb, versus 8gb or 4gb? Are there any RAM benchmarks out there?
Thanks!
SteveWell, yes, mixing & matching is fine, your system will run (of course, that assumes you have the correct kind of RAM ).
Mac memory architecture supports dual-channel memory access. Depending on the model (G5, Intel Core/Core2 Duo/Quad Core), it uses 64-bit data paths or 128-bit paths. If the DIMMS are matched, you get the benefit of the maximum speed of dual-channel access. If the DIMMS are not matched the system has to revert to asymmetric mode, which is slower. How much slower depends on all sorts of things.
Understand, that's not a complete technical explanation, but it hopefully makes the essential point. More RAM trumps matched DIMMS. However, you made a significant investment in your Core i7 iMac, if you're going to add RAM, why not buy matched DIMMS? -
Improve PC Performance transcript of Meet the Experts online chat event
On June 1st, HP hosted an online chat event on improving PC performance. Below is a transcriptof that session.
Please note that I have altered the transcript so that follow up questions areincluded in the logical order.
I am in the process of planning the next chatevent. I would love to hear what topics would interest you, what day of theweek and time is best for you, and if you think an hour is too long.
So, if you get a minute, please let me know.
Here's the transcript:
SiobhanF-HP: Welcome!
SiobhanF-HP: If you want to ask a question, you must be a member of the HP Support Forums. If you want to join, go here https://passport2.hp.com/hppcf/createuser.do
SiobhanF-HP: Our team of experts is here and ready to tackle your toughest questions.
SiobhanF-HP: Bryan_N began tinkering with computers in the early 80s with the Atari 400. He has been at HP for almost 10 years and is focused on notebooks and Wireless Wide Area Networks (WWAN.)
SiobhanF-HP: RasterBlaster, aka Randy, also began his fascination with computers 30 years ago when he spent $550 for an Atari 400. He has been addicted to desktop computers ever since and has worked at HP for 16 years.
SiobhanF-HP: Mister Do, aka Kevin, has worked for HP for 11 years. He is a desktop guy and has been ripping PCs apart to see how they work and get better performance out of them for more than 20 years.
SiobhanF-HP: Sanchertx, aka Ralph, is another 20 year PC veteran. He has worked at HP for 15 years and focuses on improving notebook and network performance.
SiobhanF-HP: Huffer, aka Steve, is an attorney by day and a PC enthusiast by night. Although Steve does not work for HP, he is an avid member of the Support Forums. His forte is troubleshooting hardware and software issues, and he uses Linux as a personal operating system instead of Windows.
DexterM: Hello people. I believe that the main reason PC's slow down is because of files leftover after program uninstalls. Many programs leave behind files that store user settings and preferences of the programs even after "complete" uninstallation. Is there any way to completely remove them during uninstallation?
Bryan_N: To DexterM Hi Dexter, Some applications have specific removal tools to fully clean them out, such as the Norton Removal Tool. You can go to symantec.com and search for "Norton Removal Tool". There are also third party applications for cleaning out abandoned registry files, such as CrapCleaner which is what I have used personally. It can be found at ccleaner.com
nseidl33: Can I add more memory to my notebook? If I do, will it void the warranty?
Sanchertx: To nseidl33 hello Nseid133, no you will not void the warranty - you should make sure the specs match up if you buy memory from someone other than HP. That said, you may be required to remove the memory in the event there is a troubleshooting session with HP Support.
aarond22: Does adding more memory really make my PC run faster? If it does, how can I figure out how much memory to add and how hard is it to do?
RasterBlaster: To aarond22 While you use your computer, all software and drivers take up memory. Windows "places" the software and drivers into the hardware memory first because it is fastest. After it runs out of hardware memory it will eventually store the excess data on the hard drive which is much slower. So the amount of memory you have will speed up your computer, but how much speed depends on several factors. Generally, for Vista 64-bit, adding up to 4 GB has the biggest speed gains. Over 4 GB doesn't speed things up all that much unless you do things like video or large graphic editing - software that uses a lot of data. You can find memory upgrade information from the product specification or motherboard specification for your model of desktop PC. This HP support article should answer everything:

animeowns: need a good gaming video card dx10 to play the newer games in hpa1720n
Huffer: To animeowns I am a big fan of the ATI HD 4800 series. It is DX10 compatible and very fast.
HPMAN10: I have a problem with my PC freezing up when I return from sleep mode. This just starting happening recently. Could it have anything to with installing Windows Vista Service Pack 2?
Huffer: To HPMAN10 Have you also added any new hardware? Sleep mode issues are often driver related. Also, some systems need to have their BIOS updated after installing Vista SP2.
HPMAN10: No I have not added new drivers. So you’re saying I should upgrade the BIOS. Isn't that a tricky to do? It could cause more problems.
Huffer: To HPMAN10 Yes, you should be careful with the BIOS upgrades but it should work well from Windows. Close all other programs and be patient with it.
HPMAN10: What about the freeze up in sleep mode? Do I need to update the BIOS for that problem too?
Huffer: To HPMAN10 Yes, there is a good chance it will help, and it cannot hurt to have the latest BIOS. Here is a good link for information: http://technet.microsoft.com/enus/library/dd335032(WS.10).aspx
Here is a good link to locate BIOS Updates for notebooks http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00042629&tmp_track_link=ot_faqs/top_issues/en_u...
Here is a good link to update the BIOS for desktops http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00007682&cc=us&lc=en&dlc=en HPMAN10: So I should update the BIOS from the HP download page?
Huffer: To HPMAN10 Yes, use the Windows-based BIOS updater. Turn off all other programs.
HPMAN10: If I have a problem with BIOS update can I do a system restore to revert back to original BIOS?
RasterBlaster: To HPMAN10 System Restore will not revert to a previous BIOS. System Restore is only for Windows - BIOS is a separate lower level function.
Huffer: To HPMAN10 BIOS is not part of the operating system, but you can flash back to an earlier version of the OS if needed. I really doubt you will have an issue. HPMAN10: I have a HP s3220n system and my Windows Media Center has a Tuner Not Installed message when I try to use live TV, I have tried everything from HP online support to Microsoft Help and nothing has solved the problem. Any suggestions?
RasterBlaster: To HPMAN10 s3220n comes with a tuner card. The no tuner found error can happen when some other TV capture software "checks out" the tuner. If you have a startup item, like webcam software that is set to hook into the Tuner card, you should go in and change the setting or remove it. Have you read this support document?http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01187871&cc=us&lc=en&dlc=en
HPMAN10: Yes I have read the HP document and tried the suggestions on it without success.
HPMAN10: I do not have a webcam.
HPMAN10: Also my PC Doctor software does not show tuner in the diagnostic program.
Mister_Do: To HPMAN10 If your tuner card is not showing up in PC Doctor, try opening the PC and reseating the tuner. If it still doesn't work, you possibly have a hardware failure.
HPMAN10: Yes I tried hardware and software recovery in HP Help and Tools. Same results NO TUNER INSTALLED.
RasterBlaster: To HPMAN10 Well, unless you did something major ... like upgrade your OS to Vista SP2... or something like that... I'd say your tuner hardware is gone. Especially if you did a system recovery. System recovery takes you back the original configuration
HPMAN10: I have removed the tuner card and reseated it without results in PC Doctor. I'll try it once more.
HPMAN10: Will a BIOS update also help the TV tuner problem?
HPMAN10: By the way I can watch programs I have recorded in the past in Media Center.
RasterBlaster: To HPMAN10 I don't think the BIOS update will help... here is the text from the site: M2N61-AR Motherboard BIOS update resolves issue with the computer shutting down and displaying message "ERROR: Unsupported CPU installed. PC will automatically shut down in a few seconds." Did you reinstall the driver from HP Help and Tools? There should at least be an unknown device in Device Manager. You older files that you are able to view are simply files that were created before you lost your tuner. “No Tuner Found” just means that Media Center cannot find the card because the card is "Check out" of the drivers are out of whack.
HPMAN10: I had tuner problem even before I installed SP2.
RasterBlaster: To HPMAN10 Well, if your tuner died and you could never get it to work after that, it might be a heat related failure. Tuners get hot... but usually, when a tuner gets too hot, you'll get some funny symptoms before it dies... like channel changing takes way too long -- to change up or down - or lots of frame skipping. IF it comes and goes - you have a software conflict problem.
amberdidi: Hi to you all, Why am I constantly receiving the following message and what can I do to correct it. "Windows cannot access the specified device, path or file. You may not have the appropriate permissions" Note: After I click Ok to this message it usually takes me to the page anyhow.
Bryan_N: To amberdidi Hi amberdidi, I'm not sure what OS you have, but this is a helpful document from Microsoft for XP: http://support.microsoft.com/?kbid=308421
amberdidi: About that message "Windows cannot access the specified device...." I am using Vista Home Edition 64 bit SP2.
Bryan_N: To amberdidi Ok, thanks for the clarification. It sounds like it is a security setting in Internet Explorer, try this please: http://support.microsoft.com/kb/959079
animeowns: Did you receive my other message?
Mister_Do: To animeowns Yes, we are working on it.
animeowns: I need a card that will fit in my computer case right now I’m using a 7900 and it’s a tight fit. Here are the specs for my motherboard http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00864946&lc=en&dlc=en&cc=us&os=2093&product=334...
animeowns: It must be about 7.8 x 3 x 4.4 inches – that’s the size of my 7900 gs, and it’s a tight fit. My motherboard is Micro-ATX: 9.6 in X 9.6 in. Please help. I want to upgrade to a nice card that will be able to play games like crysis fear 2 unreal tournament 3.
RasterBlaster: To animeowns Yeah, finding low-profile cards can be tricky. It sounds like you have the measurement. Searching the internet shopping sites for low-profile graphics cards should bring up some cards - then find one you like and work with the site to make sure it fits your measurement. HP can supply a replacement - but if it is not on HP shopping's site - you can go with other shopping sites.
animeowns: Will this video card fit in my system? http://www.newegg.com/Product/Product.aspx?Item=N82E16814127414
Mister_Do: To animeowns Sorry, I haven't tried that one personally, so I'm not sure. You'll need to make sure your current card dimensions match the new card.animeowns: Can someone please help me find a direct x 10 gaming card that will fit in my hp a1720n? The size has to be 7.8 x 3 x 4.4 inches or smaller that is the size of my pny 7900 gs and its a tight fit because the memory is real close.
RasterBlaster: To animeowns Huffer had to step out. The folks trying to help you in this chat session are from HP. We can't recommend a video card upgrade that did not already come with your PC - sorry You should post this same question into the forums under desktop PC and hardware (or video) category.
whitey: I have a ZD-7015us laptop and would like to know if the processor can be upgraded.
Huffer: To whitey I wouldn’t really recommended it because it is hard to know if it will overheat, but a Pentium 4 desktop processor will fit.
SiobhanF-HP: If you have specific product questions, the more information you give us the better we will be able to help you. Getting your exact model number; any error messages; what operating system version are you running; any recent hardware or software changes will go a long way to helping us answer your question.
amberdidi: I would like to know if NOD 32 antivirus is compatible with my Vista 64 bit. I am using Avast at the moment, but I am really interested in NOD32 or a good quality antivirus you can recommend for 64 bit. Thank you.
Huffer: To amberdidi I use Avast or AVG on Vista 64 bit systems and either works well. I have only used NOD32 on 32 bit systems. The NOD32 website will answer this question definitively.
amberdidi: Back to the freezing problem with my Vista 64 bit. I downloaded only the final version of SP2 but I have updated most of my drivers including the latest NVIDIA driver from their site. Should I also update my BIOS?
Sanchertx: To amberdidi Yes, update the BIOS.
DexterM: Other than unchecking Startup Programs from MS Configuration Utility, is there any other way to speed up startup time of a Windows PC?
RasterBlaster: To DexterM There are lots of methods. If you have Vista - go in and shut down aero, if you don't need it, make sure your temp files are cleared, etc... Here is a support document:http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00815926&cc=us&lc=en&dlc=en

Blondechica: I just bought a HP HDX16 and I am embarrassed to say I do not how to find the On button. I am using my friend’s computer and told him that I had a different problem with my computer and gave this site. Also, when I do get it turned on will it be blank. Do have to buy software? I hope this is not the first time someone has asked this question. This is all new to me. Thank you for your help.
Sanchertx: To Blondechica Hello, please hit the power button on the top left of the keyboard cover. This will illuminate to a blue color to show the unit is on. You must let the unit create the image. This means you will let it run on its own until you see the Welcome screen. The unit comes with the Vista operating system and has HP applications. It also comes with trial versions of Norton antivirus and MS Office.
Petedog11: I have the HP Pavilion a6745f Desktop PC and would like to upgrade my graphics card. I like to run high-end flight simulators. What graphics card do you recommend? Will I need to upgrade my power supply unit also? Is there a way to disable the on board graphics card that came with the computer once I install a new graphics card? Thank you.
Huffer: To Petedog11 A new power supply should not be needed. When you plug in a new video card it will automatically disable the onboard. Just be sure you have a pci-e poer connector (6 pin)
Petedog11: The power supply unit that is in my HP Pavilion a6745f Desktop PC is 300 watts I believe. My understanding is that the newer Radeon's etc...need more power. Will you please answer the remainder of my original question.....I like to run high-end flight simulators. What graphics card do you recommend? Thanks!
Huffer: To Petedog11 300 watts is a bit light. I would look for around a 500 watt psu.
mlk3742: I have a dv9000 laptop, it has 4 gigs of ram. I run Photoshop CS4. Is there any way to increase processing speed?
Sanchertx: To mlk3742 While there isn’t a switch you can turn on to make the processor run faster, you can do things like remove un-needed software and remove items from startup. Also disabling HP Advisor helps. Here is a good reference -
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00816938&lc=en&dlc=en&cc=us&lang=en&rule=13847&...
amberdidi: Since I downloaded SP2 on my Vista Home Edition I also am freezing up every so often to the point that I have to use Task Manager to end it and start over again. I have an HP Elite with 1000GB hard drive and 8192MB memory. What can I do? Thank you.
Bryan_N: To amberdidi If you downloaded the beta version of SP2 you might want to uninstall it and download the final version. If you downloaded the final version and this started with SP2, you can check the Problem Reports and Solutions feature of Vista. Just click the Start button, and type: Problem Reports, then click on the application
scribblesteve: Besides the usual cleaning up Temp files and using Disk Clean up or Defrag, how can I prevent my computer from running sluggishly? I want it to run as fast and as smooth as it did the first time I turned it on?
Mister_Do: To scribblesteve Removing startup items or keeping programs from running in the background helps a lot. And depending on what operating system you have there are multiple settings you can change to improve performance. Here are two HP support documents that list multiple ways to improve your PC performance: For XP: http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph06569&cc=us&dlc=en&lc=en&jumpid=reg_R1002_USE...
For Vista: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00815926&cc=us&dlc=en&lc=en&jumpid=reg_R1002_US...
bjm: I have a Compaq Presario A931NR Notebook BIOS F.32 Software Driver download site displays F.34 I don't know if I should Update to F.34 because F.32 is not listed as a previous version, and I don't know if I can go from F.32 to F,34 without F.33
Huffer: To bjm No problem. You can easily skip a level of BIOS update and go right to 3.4.
bjm: Need to know if I should update my BIOS
Huffer: To bjm The update will work, but I really need to know what your problem is to assess whether the BIOS update is necessary.
bjm: HP Updates report no available Updates so how do I know if I need Update other than what is presented on Software Driver download page
Mister_Do: To bjm If HP Update says you don't have any new updates, then your PC is up to date with the latest drivers. If you by chance see a software or driver file on you product support page, and it's newer than what you have. You can install it, but if your PC is running fine, you may not want to bother.
bjm: Huffer asked why is BIOS update necessary. I would ask why does Software Update site show an Update if it's not necessary? HP Update is not working to report BIOS updates. 13 months and no Updates ever. So, all I have to go by is Software Update site which report newer BIOS with Enhancements to Security. Why would Total Care Advisor, HP Health Check and HP Update not have even one Update or info after 13 months of service?
RasterBlaster: To bjm The software BIOS update page on hp.com/customercare should tell you what the BIOS update fixes or improves. If your system is running well or the BIOS update page does not list a fix for your problem - don't update the BIOS. That's my opinion anyway. BIOS updates do introduce a level of risk. For example if you have a power outage while updating the BIOS, the PC will require service. So ... if in doubt, don't do it unless you know it resolves an issue.
bjm: The BIOS Update to F.34 is stated as having Security Enhancements. Does the System Info refresh with a BIOS update or is System Info static
Mister_Do: To bjm Where are you viewing the System Info? From the BIOS itself, from "Properties" under "Computer", etc.? Here’s good document on Locating HP Software, Driver and BIOS Updates:

puter_student: I sent my hp Mini 1000 (Win XP) into service about two weeks ago. I gave a lady friend a 1120NR (Mi on Linux) yesterday. As she is a geographic distance, and using a different OS, how would you suggest I assist her by telephone. And, once she establishes solid Internet access, is it best to send her e-mail or instant messages?
Bryan_N: To puter_student Hi Puter_student, you have several choices since HPMI supports MSN messenger and other chat programs via the "pidgeon" application, and it also comes preinstalled with Skype. You can install either of those on your XP unit. Skype also allows you to use a webcam at the same time.
puter_student: Sorry, I stated my question badly. I did not mean to ask about the communications technology. I meant the information resources available online -- to both her and me -- WRT setup, configuration (if needed), etc. The realization came to me earlier today that I cannot "walk" her thru it by simply telling her what I see on my own machine as I take certain actions [other, of course, than accessing appropriate documents about her model]. Can you point me in the right direction to those resource documents?
Bryan_N: To puter_student For support documents you can start here:
http://h10025.www1.hp.com/ewfrf/wc/product?product=3860346&lc=en&cc=us&dlc=en&lang=en&cc=us
puter_student: I clicked the link you supplied. Doing so took me out of this chat, but did not get me where you were trying to send me. Now, when I return to the chat, I no longer have the earlier session history. When will it be posted, and where can I find the whole chat session later?
Bryan_N: To puter_student The transcript will be posted on the boards within 48 hours after this event. I got to the link by going to hp.com, and searching for support on "mini 1110nr" http://h10025.www1.hp.com/ewfrf/wc/product?product=3860346&lc=en&cc=us&dlc=en&lang=en&cc=us
The MI desktop is based on Ubuntu, and you can also find lots of general Ubuntu information on external forums Certain applications have support externally as well, such as the Firefox browser.
mlk3742: to Sanchertx: Can I swap out or replace the graphics card to speed up graphic intensive demands such as Photoshop?
Sanchertx: To mlk3742 Hello - not with our notebooks. They are either attached to system board or a daughter board, which is then attached to the system board.mlk3742: to Sanchertx: So there is no way from a hardware approach to increase speed? The only time I notice my lap slows down is processing large files, i.e. photos, or while performing image edits in Photoshop. After increasing RAM, everything else has speeded up noticeably. My laptop has more than half the hard drive space free.
Sanchertx: To mlk3742 Hardware wise you can get a faster hard drive - example move from a 5400 rpm to 7200 RPM - Also make sure you have the latest BIOS update. These usually have maintenance modifications to resolve potential problems and tweak the hardware.mlk3742: to Sanchertx: How and or where do I get a BIOS upgrade? Do you have a recommendation for which hard drive to get? Will any aftermarket drive fit in my laptop?
Sanchertx: To mlk3742 Hello – this document Locating HP Software, Driver and BIOS Updates should help http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00042629&tmp_track_link=ot_faqs/top_issues/en_u... I cannot recommend a 3rd party - aftermarket drive - but there are many available. A good place to look is notebookforum.com.
scribblesteve: My battery is fine, but the HP Battery check doesn't recognize it. I have the most updated versions of BIOS, Help and Support and sp41862, and it still doesn't recognize it. I'm running Vista32bit on an HP pavilion dv6704nr. What else can I try to check and prolong the life of my battery?
Bryan_N: To scribblesteve Hi scribblesteve, ensure the battery is charged and the AC adaptor is plugged in when testing. If that doesn't work, you can do some basic battery life steps. These are found at http://h20239.www2.hp.com/techcenter/battery/Battery_max.htm and also at http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00821429&cc=us&dlc=en&lc=en&jumpid=reg_R1002_US...
DexterM: What tweaks do you guys usually do on your Windows PC's to ensure optimal PC performance?
Bryan_N: To DexterM Hi DexterM, I uninstall any applications I don't use, run Microsoft and HP updates, keep a good antivirus installed, and also I personally use a third party application called ccleaner. I back up my unit in full every month as well just in case.
amdkenworth: Hi I have an HP that has a on board video card and it won’t show any video when its turned on???
RasterBlaster: To amdkenworth First thing you should do is try connecting another monitor to see if it is related to the monitor or the video on the motherboard. Here is document that you should check out: http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph04760&lc=en&dlc=en&cc=us&lang=en&rule=3950&pr...
jest1: My notebook has a short battery life. Is there something I can do?
Sanchertx: To jest1 A: There are several things you can do to extend battery life such as changing your power plan, calibrating your battery to increase capacity, or shutting off unused features in the OS. Here is an excellent document on notebook battery usage that will walk you through your options step by step http://tinyurl.com/57x38x
Dominick_7: Hi I have an HDX 9000t and was wondering if anyone knew if/how I could upgrade the graphics card, to say an MXM GPU?
Bryan_N: To Dominick_7 Hi Dominick_7, there isn't a way to upgrade the video card itself. You can ensure you have the latest drivers by visiting hp.com and checking drivers, and keep your overall system optimized with standard PC Tune up steps such as this document: c00034290 - HP Notebook PCs - Improving the Performance of Your Notebook PC
Dominick_7: From what I understand, an HP tech told me MXM has on board BIOS which doesn’t depend on the BIOS from the motherboard. What leads you to say it can’t be done?
Bryan_N: To Dominick_7 The video card is separate, but not replaceable as it is directly attached to the system board
Dominick_7: Can't the same be said about the processor? Yet I know people who have updated their processors, and GPUs when they upgrade them from an ATI to the 8800M GTS NVIDIA GPU? If you could please elaborate in a more detailed fashion as to what the obstacles are I'd appreciate it. Is that the ONLY reason why you say it can't be done? Because it’s directly connected to the motherboard? If that was insurmountable wouldn't that make it impossible to upgrade the ATI GPU in lower specd HDXs to the 8800 NVI...
Bryan_N: To Dominick_7 The CPU is not soldered onto the system board, so it is replaceable. The GPU/Graphics card is soldered onto the system board and is not replaceable.
SSPatrick: HP Total Care Advisor is giving me warnings - How do I clear these up?
Sanchertx: To SSPatrick Click on the PC Update button inside of Advisor to check for and run updates.

laurensw: I installed antivirus software and now my PC is running really slow - what should I do?
Bryan_N: To laurensw Hi Laurensw, It often helps to ensure the original antivirus software was fully removed. One possible solution is to use the Norton Removal Tool to completely remove the trial version of Norton that shipped with your PC.
rdewing: My PC is about a year old and it is getting slower and slower. Do I have a virus? Is there something that I can do to make run faster?
Mister_Do: To rdewing It is tough to say why your PC is running slowly, but there are some things you can do that may help its performance. Check out this web site for step by step instructions on basic PC care. http://h20239.www2.hp.com/techcenter/pctuneup/ HP also offers free online classes to teach you how to tune up your XP or Vista PC.

Mister_Do: To jest1 The first two things I would consider doing would be to 1) add more memory to your PC (unless you already have max memory), and 2) I would change my Startup program and process settings. Here are a few HP Support documents that explain how to prevent unnecessary programs from running at startup: For Vista: http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c00813419 For Vista: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00819747&cc=us&lc=en&dlc=en For XP: http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph07149&cc=us&lc=en&dlc=en
SiobhanF-HP: We only have time for one more question. If we did not get to your question, please post it on the Notebook or Desktop boards.
jest1: I think I have a notebook battery that was part of a recent recall, what do I do about this?
Mister_Do: To jest1 Visit the HP Notebook PC Battery Pack Replacement Program Web site at: http://www.hp.com/support/BatteryReplacement for additional information and to determine if your battery is part of the program.
jest1: How can I find out the maximum amount of memory my system can accept?
Mister_Do: To jest1 HP has product specifications for your PC on its web site. Go to www.HP.com and click on Software Driver and enter your exact PC model name. You must give the specific model number, ex dv9009nr, and not the series number, ex dv9000. Click on the document that references Product Specifications at the top of the list of articles. You will get a detailed breakdown of your system including microprocessor, graphics card, and the maximum amount of memory you can load onto your PC.
SiobhanF-HP: We are ending the chat event. Thank you for coming. We hope you found it worthwhile. I will be posting a transcript of the event in announcement section at the top of the Notebook and Desktop boards. Please feel free to continue these conversations on the Forums.

Re: How to Improve the performance on Rollup of Aggregates for PCA Infocube
Hi BW Guru's,
I have unresolved issue and our team is still working on it.
I have already posted several questions on this but not clear on how to reduce the time on Rollup of Aggregates process.
I have requested for OSS note and searching myself but still could not found.
Finally i have executed one of the cube in RSRV with the database selection
"Database indexes of an InfoCube and its aggregates" and got warning messages i was tried to correct the error and executed once again but still i found warning message. and the error message are as follows: (this is only for one info cube we got 6 info cubes i am executing one by one).
ORACLE: Index /BI0/IACCOUNT~0 has possibly degenerated
ORACLE: Index /BI0/IPROFIT_CTR~0 has possibly degenerated
ORACLE: Index /BI0/SREQUID~0 has possibly degenerated

i don't know how to move further on this can any one tell me how to tackle this problem to increase the performance on Rollup of Aggregates (PCA Info cubes).
every time i use to create index and statistics regularly to improve the performance it will work for couple of days and again the performance of the rollup of aggregates come down gradually.
Thanks and Regards,
Venkathi,
check in a sql client the sql created by Bi and the query that you use directy from your physical layer...
The time between these 2 must be 2-3 seconds,otherwise you have problems.(these seconds are for scripts that needed by Bi)
If you use "like" in your sql then forget indexes....
For more informations about indexes check google or your Dba .
Last, i mentioned that materialize view is not perfect,it help a lot..so why not try to split it to smaller ones....
ex...
logiacal dimensions
year-half-day
company-department
fact
quantity
instead of making one...make 3,
year - department - quantity
half - department - quantity
day - department - quantity
and add them as datasource and assign them the appropriate logical level at bussiness layer in administrator...
Do you use partioning functionality???
i hope i helped....

I'm about to buy a 27" i-Mac. I would like to connect my 30" Cinema Display to it as a second monitor. What will I need to do that? Will this slow down the overall performance?
The new iMacs do not come with a MiniDisplayPort, they have Thunderbolt, so unless you are talking about purchasing one of the previous generation iMacs such as this refurbished model in the online Apple store, it won't work. And yes, if you are going to get the full range of video resolutions you will need the Dual-Link version.
For details see the store's web page on the Dual-Link display adapter. -
How to improve the performance of adobe forms
Hi,
Please give me some suggestions as to how to improve the performance of adobe form?
Right now when I' am doing user events it is working fine for first 6 or 7 user events. From the next
one it is hanging.
I read about Wizard form design approach, how to use the same here.
Thanks,
AravindHi Otto,
The form is created using HCM forms and processes. I' am performing user events in the form.
User events will doa round trip, in which form data will be sent to backend SAP system. Processing will
happen on the ABAP side and result will appear on the form. First 6 or 7 user events works correctly,
the result is appearing on the form. Around 8 or 9th one, the wait symbol appears and the form is not
re-rendered. The form is of size 6 pages. The issue is not coming with form of size 1 page.
I was reading ways to improve performance during re-rendering given below.

It talks about wizard form design approach. But in SFP transaction, I am not seeing any kind of wizard.
Let me know if you need further details.

Help to improve the performance of a procedure.
Hello everybody,
First to introduce myself. My name is Ivan and I recently started learning SQL and PL/SQL. So don't go hard on me. :)
Now let's jump to the problem. What we have there is a table (big one, but we'll need only a few fields) with some information about calls. It is called table1. There is also another one, absolutely the same structure, which is empty and we have to transfer the records from the first one.
The shorter calls (less than 30 minutes) have segmentID = 'C1'.
The longer calls (more than 30 minutes) are recorded as more than one record (1 for every 30 minutes). The first record (first 30 minutes of the call) has segmentID = 'C21'. It is the first so we have only one of these for every different call. Then we have the next (middle) parts of the call, which have segmentID = 'C22'. We can have more than 1 middle part and again the maximum minutes in each is 30 minutes. Then we have the last part (again max 30 minutes) with segmentID = 'C23'. As with the first one we can have only one last part.
So far, so good. Now we need to insert these call records into the second table. The C1 are easy - one record = one call. But the partial ones we need to combine so they become one whole call. This means that we have to take one of the first parts (C21), find if there is a middle part (C22) with the same calling/called numbers and with 30 minutes difference in date/time, then search again if there is another C22 and so on. And last we have to search for the last part of the call (C23). In the course of these searches we sum the duration of each part so we can have the duration of the whole call at the end. Then we are ready to insert it in the new table as a single record, just with new duration.
But here comes the problem with my code... The table has A LOT of records and this solution, despite the fact that it works (at least in the tests I've made so far), it's REALLY slow.
As I said I'm new to PL/SQL and I know that this solution is really newbish, but I can't find another way of doing this.
So I decided to come here and ask you for some tips on how to improve the performance of this.
I think you are getting confused already, so I'm just going to put some comments in the code.
I know it's not a procedure as it stands now, but it will be once I create a better code. I don't think it matters for now.

It's my first post here so hope this is the right sub-forum.
I tried to explain everything as deep as possible (sorry if it's too long) and I kinda think that the code got somehow hard to read with all these comments. If you want I can remove them.
I know I'm still missing a lot of knowledge so every help is really appreciated.
Thank you very much in advance!Atiel wrote:
Thanks for the suggestion but the thing is that segmentID must stay the same for all. The data in this field is just to tell us if this is a record of complete call (C1) or a partial record of a call(C21, C22, C23). So in table2 as every record will be a complete call the segmentID must be C1 for all.Well that's not a problem. You just hard code 'C1' instead of applying the row number as I was doing:

Another thing is that, as I said above, the actual table has 120 fields. Do I have to list them all manually if I use something similar?If that's what you need, then yes you would have to list them. You only get data if you tell it you want it. ;)
Of course if you are taking the start_date_of_call, callingnumber and callednumber as the 'key' to the record, then you could join the results of the above back to the original table1 and pull out the rest of the columns that way...

SQL>Of course this is pulling back the additional columns for the record that matches the start_date_of_call for that calling/called number pair, so if the values differed from row to row within the calling/called number pair you may need to aggregate those (take the minimum/maximum etc. as required) as part of the first query. If the values are known to be the same across all records in the group then you can just pick them up from the join to the original table as I coded in the above example (only in my example the data was different across all rows). -
Need help in improving the performance for the sql query
Thanks in advance for helping me.
I was trying to improve the performance of the below query. I tried the following methods used merge instead of update, used bulk collect / Forall update, used ordered hint, created a temp table and upadated the target table using the same. The methods which I used did not improve any performance. The data count which is updated in the target table is 2 million records and the target table has 15 million records.
Any suggestions or solutions for improving performance are appreciated
SQL query:
update targettable tt
set mnop = 'G',
where ( x,y,z ) in
select a.x, a.y,a.z
from table1 a
where (a.x, a.y,a.z) not in (
select b.x,b.y,b.z
from table2 b
where 'O' = b.defg
and mnop = 'P'
and hijkl = 'UVW';987981 wrote:

The methods which I used did not improve any performance. And that meant what? Surely if you spend all that time and effort to try various approaches, it should mean something? Failures are as important teachers as successes. You need to learn from failures too. :-)
The data count which is updated in the target table is 2 million records and the target table has 15 million records.Tables have rows btw, not records. Database people tend to get upset when rows are called records, as records exist in files and a database is not a mere collection of records and files.
The failure to find a single faster method with the approaches you tried, points to that you do not know what the actual performance problem is. And without knowing the problem, you still went ahead, guns blazing.
The very first step in dealing with any software engineering problem, is to identify the problem. Seeing the symptoms (slow performance) is still a long way from problem identification.
Part of identifying the performance problem, is understanding the workload. Just what does the code task the database to do?
From your comments, it needs to find 2 million rows from 15 million rows. Change these rows. And then write 2 million rows back to disk.
That is not a small workload. Simple example. Let's say that the 2 million row find is 1ms/row and the 2 million row write is also 1ms/row. This means a 66 minute workload. Due to the number of rows, an increase in time/row either way, will potentially have 2 million fold impact.
So where is the performance problem? Time spend finding the 2 million rows (where other tables need to be read, indexes used, etc)? Time spend writing the 2 million rows (where triggers and indexes need to be fired and maintained)? Both?
