Poor performance by Matlab and Windows benchmark tests
Hello
I have a Lenovo Thinkpad W520 with Windows 7 64bit installed. Compared to other Notebooks with comparable hardware, my Lenovo is very slow. To prove my thought, I carried through a Matlab (64bit) benchmark test and the Windows 7 benchmark test. In both tests, my Lenovo was worse than the other notebooks. During the tests I set the Power Manager to performance and activated the Lenovo turbo boost.
Now I want to ask, if there are any settings, perhaps in the bios, to speed the laptop up? Or why result such a bad performance although the hardware is very good?
Thanks for your help
Solved!

Thank you very much for your reply!
I dated up the BIOS from version 1.27 to 1.32. Now the benchmark tests all look great!!
Thanks

Poor performance with WebI and BW hierarchy drill-down...
Hi
We are currently implementing a large HR solution with BW as backend
and WebI and Xcelcius as frontend. As part of this we are experiencing
very poor performance when doing drill-down in WebI on a BW hierarchy.
In general we are experiencing ok performance during selection of data
and traditional WebI filtering - however when using the BW hierarchy
for navigation within WebI, response times are significantly increasing.
The general solution setup are as follows:
1) Business Content version of the personnel administration
infoprovider - 0PA_C01. The Infoprovider contains 30.000 records
2) Multiprovider to act as semantic Data Mart layer in BW.
3) Bex Query to act as Data Mart Query and metadata exchange for BOE.
All key figure restrictions and calculations are done in this Data Mart
Query.
4) Traditionel BO OLAP universe 1:1 mapped to Bex Data Mart query. No
calculations etc. are done in the universe.
5) WebI report with limited objects included in the WebI query.
As we are aware that performance is an very subjective issues we have
created several case scenarios with different dataset sizes, various
filter criteria's and modeling techniques in BW.
Furthermore we have tried to apply various traditional BW performance
tuning techniques including aggregates, physical partitioning and pre-
calculation - all without any luck (pre-calculation doesn't seem to
work at all as WebI apparently isn't using the BW OLAP cache).
In general the best result we can get is with a completely stripped WebI report without any variables etc.
and a total dataset of 1000 records transferred to WebI. Even in this scenario we can't get
each navigational step (when using drill-down on Organizational Unit
hierarchy - 0ORGUNIT) to perform faster than minimum 15-20 seconds per.
navigational step.
That is each navigational step takes 15-20 seconds
with only 1000 records in the WebI cache when using drill-down on org.
unit hierachy !!.
Running the same Bex query from Bex Analyzer with a full dataset of
30.000 records on lowest level of detail returns a threshold of 1-2
seconds pr. navigational step thus eliminating that this should be a BW
modeling issue.
As our productive scenario obviously involves a far larger dataset as
well as separate data from CATS and PT infoproviders we are very
worried if we will ever be able to utilize hierarchy drill-down from
WebI ?.
The question is as such if there are any known performance issues
related to the use of BW hierarchy drill-down from WebI and if so are
there any ways to get around them ?.
As an alternative we are currently considering changing our reporting
strategy by creating several higher aggregated reports to avoid
hierarchy navigation at all. However we still need to support specific
division and their need to navigate the WebI dataset without
limitations which makes this issue critical.
Hope that you are able to help.
Thanks in advance
/Frank
Edited by: Mads Frank on Feb 1, 2010 9:41 PMHi Henry, thank you for your suggestions although i´m not agree with you that 20 seconds is pretty good for that navigation step. The same query executed with BEx Analyzer takes only 1-2 seconds to do the drill down.
Actions
suppress unassigned nodes in RSH1: Magic!! This was the main problem!!
tick use structure elements in RSRT: Done it.
enable query stripping in WebI: Done it.
upgrade your BW to SP09: Has the SP09 some inprovements in relation to this point ?
use more runtime query filters. : Not possible. Very simple query.
Others:
RSRT combination H-1-3-3-1 (Expand nodes/Permanent Cache BLOB)
Uncheck prelimirary Hierarchy presentation in Query. only selected.
Check "Use query drill" in webi properties.
Sorry for this mixed message but when i was answering i tryied what you suggest in relation with supress unassigned nodes and it works perfectly. This is what is cusing the bottleneck!! incredible...
Thanks a lot

Poor performance - QT Player and Safari
Ok, so I've been ignoring this issue on my computer for the longest time and I think it's time I got to the bottom of it.
I'm using a Quicksilver G4, 733MHz, with 896MB RAM.
Now, previously, prior to upgrading to Tiger, using Panther and QT 6.5 something, Quicktime worked pretty much flawlessly. I was so happy with it. After upgrading to Tiger such a long time ago, I noticed QT 7 wasn't nearly up to par and its performance was very bad.
The real issue here is this: Whenever I watch a streaming movie downloaded from the internet, in Safari, it runs choppy. Choppy as in the framerate stutters considerably, the video will pause while the audio still plays, and it basically renders the video unwatchable. The workaround I've been doing all this time, is: downloading the video onto my desktop and playing it through VLC. (Which it does absolutely flawlessly, mind you.)
Oh but it gets better - when I play these EXACT same video files in Quicktime Player - I get "improved" performance, but it still does the same thing: choppy video playback. Now, when I play these same streaming files in Firefox - they work, smooth as a baby's bottom. Quicktime's streaming plug-in works great. Doesn't make sense...
On top of ALL that: After this problem was already engraved in my head after trying numerous troubleshooting (reinstalling latest versions of Quicktime, clearing caches, making a test user account, A&I, etc....) I eventually upgraded my computer, and put another internal 250GB HD in it. So I was basically starting from scratch - a complete erase and install of the HD.
Lo and behold, Quicktime STILL did it. - same exact problem. So I gave up for a while and have been using VLC ever since. Or Firefox.
So that's my problem guys - any suggestions would be nice, or if you'd like, just tell me to keep using VLC and/or Firefox as workarounds and don't even try to fix it. ¬_¬
Quicksilver Powermac G4 733Mhz Mac OS X (10.4.8) 894MB RAM, 250GB & 40GB HDs
Quicksilver Powermac G4 733Mhz Mac OS X (10.4.8) 896 MB RAM, 250GB & 40GB HDI do not use Safari. However, I found this troubleshooting technique in the MacAddict Magazine December 06 issue:
To fix a QT related problem w/Safari, quit Safari & look in the /Library/Internet Plug-Ins folder (this is the Library folder at the root level of your HD, not the one inside your Users/user name folder).
Try removing the VLC Plugin.plugin (if you have it) & QT Plugin.plugin files from this folder, & then relaunch Safari. If the problem isn’t fixed, a different plug-in may be to blame. Keep removing files from this folder (start with any third-party plug-ins that are present) until the problem disappears.
Replace the plug-ins that don’t cause any problems. -
Poor performance with Yosemite and early 2009 Mac Pro
I have an early 2009 Mac Pro with the following specs:
- 2.66 GHz Quad Core Intel Xeon
- 10 GB of 1066 MHz RAM
- NVidia GeForce GT 120 512 MB
- 256 MB solid state drive for my system partition
- Two monitors connected, each at 1680x1050 resolution
Back when I was running OS X 10.7 or 10.8 I found that for every day tasks the performance using my computer was adequate. However, starting around 10.9, and even worse since upgrading to 10.10, thinks have gotten painfully slow. To give an example, activating Mission Control can take upwards of four seconds, with the animation being very choppy. Changing tabs on a Finder window can take two seconds for the switch to happen. Just switching between different windows, it can take several seconds for a window to activate. It's gotten to the point where I'm having difficulty working. So I'm thinking of upgrading some of my hardware.
Given my specs the weakest link seems to be my graphics card, and all of these issues do seem to be related to graphics. So my questions are:
- Do you think upgrading my graphics card will substantially improve things, and is there anything else I should upgrade?
- Is this slowness just the result of the computer being nearly six years old, and no upgrades will really improve things that much?
Thanks in advance!Between Setup Assistant, and your existing system "untouched" (or use CCC if say you want to use an existing SSD for the system) there is no reason it should be a lot of work setting up. Have you ever used Migration or Setup? it has also gotten better.
Also, having 10.9.5 on another drive and running DU - and TRIM _now_ would be helpful.
Looking at just what gremlins you have running around inside your current system is not bad but.... sometimes the "long road" turns a shortcut into a dead end, and avoiding doing what seems the long road and hardest gets you where you want to go: a solid stable system.
Less is more. Most systems have more than needed and they get in the way and can cause trouble. Even handy "widgets" and those things that monitor system functions, even disk status. Which is why I like seeing a separate small system maintenance volume just for the weekly checkup. 30GB is more than enough so just slice out a partition somewhere - on another drive/device.
Those things, more so than and a lot cheaper than a new GPU. If your SSD is two years old, the 840 EVO from Samsung is down under $120 for 250GB, or use one for Lightroom / Aperture / iPhoto or scratch.
One person was complaining about sluggish window issue and thought it was the driver. Turned out It happened in ONE APP, not everywhere - very telling - and the app in question needs update. Adobe updated CC (for Windows) last month to finally support dual Dxx and some of the newer AMD GPUs - can the mac be far behind?
10GB RAM? that would not be 3 x 4GB or any combination using triple channel memory. -

Poor performance after format and OS install.

Win7 64
Yesterday I formatted my drive and installed win7 64, after installing all the (old) drivers on the MSI website (link below), in the correct order, then waiting a good 8 hours for all the windows updates to install, I booted up WoW and found horrible FPS. I ran 3dmarks 11 and scored a dismal 2600 with my graphic and combined scores around 2500 and the physics at the normal 8500.
Searched online for some solutions, put the 680m as the default for WoW and 3dmarks but with no difference. I went ahead and got the latest drivers for the 680m off the Nvidia website and saw no improvement.
I did not install any utilities from the MSI website, are any of them needed for the proper function of the laptop or are they all fluff?
I did not install any firmware either, Is it needed?
Should I download the latest drivers for all the components or stick with MSI's?
The laptop itself is extremely quick when not needing graphical power.
Thank you.The following factors will affect the performance score:
- Using AC or DC.
- Power plans (Windows). High-performance or Balanced mode.
- Numbers of background processes.
- Wi-Fi/BT on or off.
- Improvements from newer BIOS, EC, or Video BIOS versions.
- Screen brightness (slightly affected).
Your score is indeed a little lower. Check the points above to improve it. -
Poor performance when Distinct and Order By Used

Poor performance in iMovie and iDVD in the UK. Anyone noticed?
Hello everyone,
I've made several very successful DVDs using stills for UK TVs with the PAL format, 1280 x 720 pixels. I'm running iLife 06, latest everything for Tiger.
I use Keynote - export to Quicktime, custom settings, HDV 720p, Apple intermediate codec, 25 fps, for graphical introduction pieces.
I also use Photo 2 Movie for the stills with pan & scan etc., again Pal format, exported for iMovie.
These elements are then dropped into an iMovie project for the relevant subject and audio added. This project is then saved as a Full Quality QuickTime movie and dropped into a final assembly iMovie project, which is in turn sent to iDVD. This keeps the visual timeline manageably short.
On my last projects, this gave a stunning result. 4 Quicktime upgrades later and using the same procedure, motion now seems slightly jerky even though all the frame rates for PAL are correct. Before I complete the project, has anyone else noticed this drop in quality? I don't want to waste time if I should be doing something differently.
I've also noticed that once again, you can't use purchased music in an iMovie project - it freezes the video. Apple had this bug before and fixed it, now it's back. I don't know whether the two are connected.
Can anyone give me any advice? Thanks.Why are you making a HD project if you then burn it as standard definition DVD via iDVD?
iDVD has to downsample the HD to SD. I haven't experimented how well iDVD manages to do that.
Have you tried to do a standard definition iMovie PAL project and feed that to a PAL iDVD project? Yes, I strongly recommend using Photo To Movie's High Quality PAL DV export for the slideshows because iMovie's slideshows are, erm, suboptimal in quality. -
Hello,
I am experiencing poor performance with a virtualized Windows 8.1 Enterprise. When I do not have the "RemoteFX 3D Video Adapter" added to the VM Windows 8.1 is more responsive (with simple things like moving windows around the desktop) but of course
I don't get the benefits of RemoteFX.
I have a bench system setup to test RemoteFX in Server 2012R2.
Host Server:
Windows Server 2012 R2
Core i5-4570 (3.2Ghz)
8GB RAM
SSD for VM's
nVidia GTX750 Ti (tested with other nVidia and ATI cards with the same result)
The VM:
Windows 8.1 Ent
4 vCPU's
4GB RAM (non dynamic)
RemoteFX 3D Video ADapter w/ 4 Monitors and 1920x1200 resolution
The RDP clients I have tested with are Windows 8.1 Enterprise and Windows 7 Ultimate SP1 (RDP client says version 6.3.9600 and Remote Desktop Protocol 8.1 supported). This is all tested on a Gig LAN and the quality of the connection says "the remote
computer is excellent and UDP is enabled".
The event viewer on the 8.1 VM shows RemoteFX being used as does the performance counters on the host. Everything is slow and does not really run as expected other then Windows Media Player. Playing HD movie on Windows Media Player it looks great but if
I open the same video in VLC it is choppy. Youtube is also choppy.
I have tried disabling the NIC offload in the adapter and in the registry as seems to be recommended in a few different forums without success.
It seems to me that Windows Media Redirection works however the RemoteFX Media Streaming is not kicking in when required or it's not working well.
Using Windows Media Player I am getting average encoding time of about 2ms and frames skipped/second - Insufficient Server Resources is average 18. The other frames skipped options are 0. The total CPU utilization on the server is about 6%. (subjectively
quality seems a little less then with VLC but audio is in better sync)
Using VLC I am getting average encoding time of about 51ms and frames skipped/second - Insufficient Server Resources is average 0.1. The other frames skipped options are 0. The total CPU utilization on the server is about 25%.
On other higher resolution movies using VLC I get some average encoding time is almost 100ms.
I ran the Unigine Heaven Benchmark 4.0 test the DirectX performance on the VM with RemoteFX. With the VM I got a score of 392 and it's pretty jerky. On the host, not using RDP, I got a score of 1108 and it was nice and smooth.
I assume that the perceived slowness is because of the Average Encoding Time. What can I do to improve this?
Thank you for your time,
SeamusHi,
Thank you for posting in Windows Server Forum.
You can run below mention command from PowerShell.
Import-Module RemoteDesktopServices
Add-VMRemoteFx3dVideoAdapter -VMName nameofcomputer
SET-VMRemoteFx3dVideoAdapter –VMName nameofcomputer
After that the adapter should work.
In addition please check the article to see RemoteFx Compatible GPUs.
GPU Requirements for RemoteFX on Windows Server 2012 R2
RemoteFX vGPU Setup and Configuration Guide for Windows Server 2012
Hope it helps!
Thanks.

Poor performance of Premiere Pro on 2013 Mac Pro
A month ago I bought a 2013 Mac Pro mostly for running Premiere Pro CC. The configuration is 6 cores @ 3.5 GHz, 64 GB RAM, 2 x D700 graphics, 1 TB internal SSD. It runs OS X Mavericks 10.9.4.
I tried Premiere Pro CC today for the first time. The input--entirely stored on the internal SSD; no external disk was even connected--was about 100 clips shot as AVCHD (1080p25 PAL) at 24 Mbps.
I edited this in Premiere Pro and added small adjustments (mostly changes of levels) in about 20 clips. The rest had no adjustments. There were no transitions applied. For the most part, it just had to copy the trimmed input clips to the output.
I queued this for Adobe Media Encoder CC at H.264, 1080p25, @ 24 Mbps VBR 2 pass. Audio was 192 kbps, 48 kHZ,stereo. The output was written to the internal SSD.
While encoding, the CPU was running 50-70% idle (!!!) so it was using only 2-3 cores and half the memory (32GB) was unused. It certainly wasn't trying very hard. No other programs except Premiere, AME, and the activity monitor were open during encoding and I was just sitting there watching it lumber along.
The time to encode the timeline of 9:47 was 21:28. That is 2.2x real time. My 4-year-old Windows machine using CS6 could do that. What's wrong? Should Premiere Pro be this slow on hardware this fast? Is there some secret box "Use all the cores and all allowed memory" that I have to check (I set the preferences to allow Adobe to use 52 GB). Does Premiere get tired in the evenings? The internal SSD runs at 900 MB/s and there was no transcoding to do. What was going on?
This is my first test of Premiere and it is kind of disappointing. Did I just waste 6500 euros on the Mac Pro or am I using the wrong settings. Any advice is welcome.
Thanks.Yes, should be great if someone put some light in all this performance thing in the new mac pro, I just did a test, 3 video tracks with 4K Red footage, 50% of opacity each one and I just play the 2 min sequence, and Premiere started to drop frames at half resolution playback and when I changed to full resolution playback the sequence was unplayable, I mean, they sold this MacPro/Premiere workflow as the way to edit 4K without compromises and now we are not capable to deliver jobs because the poor performance... and I'm not talking now about the constant crashes and freezes, I'm talking about that we can't play just 3 tracks without any effect.
Would be great if someone put some light on this, maybe we are blaming adobe and it's apple's fault and we should go to the apple store to return the machine... I did test on the Mac and looks OK, I'm more than confuse about this... -
Story
I've been using arch for the past four months, dual booting with my old Windows XP. As I'm very fond of Flash games and make my own programs with a cross-platform language, I've found few problems with the migration. One of them was the Adobe Flash Player performance, which was stunningly bad. But everyone was saying that was normal, so I left it as is.
However, one special error always worried me: a seemingly randomly started siren sound coming from the motherboard speaker. Thinking it was a alarm about some fatal kernel error, I had been solving it mostly with reboots.
But then it happened. While playing a graphics intensive game on Windows quickly after rebooting from Arch, the same siren sound started. It felt like a slap across the face: it was not a kernel error, it was an motherboard overheat alarm.
The Problem
Since the computer was giving overheat signs, I started looking at things from another angle. I noticed that some tasks take unusually long times in Arch (i.e.: building things from source; Firefox / OpenOffice startup; any graphics intensive program), specially from the Flash Player.
A great example is the game Penguinz, that runs flawlessly in Windows but is unbearably slow in Arch. So slow that it alone caused said overheat twice. And trying to record another flash game's record using XVidCap things went so bad that the game halved the FPS and started ignoring key presses.
Tech Info
Dual Core 3.2 processor
1 gb RAM
256 mb Geforce FX 5500 video card
Running Openbox
Using proprietary NVIDIA driver
TL;DR: poor performance on some tasks. Flash Player is so slow that overheats CPU and makes me cry. It's fine on Windows.
Off the top of my head I can think up some reasons: bad video driver, unwanted background application messing up, known Flash Player performance problems and Actionscript Linux/Arch-only bug.
Where do you think is the problem?jwcxz wrote:Have you looked at your process table for any program with abnormal CPU usage? That seems like the logical place to start. You shouldn't be getting poor performance in anything with that system. I have a 2.0GHz Core 2 Duo and an Intel GMA 965 and I've never had any problems with Flash. It's much better than it used to be.
Pidgin scared me for a while because it froze for no apparent reason. After fixing this, the table contains this two guys here:
%CPU
Firefox: 80%~100%
X: 0~20%
Graphic intensive test, so I think the X usage is normal. It might be some oddity at the Firefox+Linux+Flash sum, maybe a conflict. I'll try another browser.
EDIT:
Did a Javascript benchmark to test both systems and browsers.
Windows XP + Firefox = 4361.4ms
Arch + Firefox = 5146.0ms
So, it's actually a lot slower without even taking Flash into account. If someone knows a platform-independent benchmark to test both systems completely, and not only the browser, feel free to point out.
I think that something is already wrong here and the lack of power saving systems only aggravated the problem, causing overheat.
EDIT2:
Browser performance fixed: migrated to Midori. Flash stills slower than on Windows, but now it's bearable. Pretty neat browser too, goes better with the Arch Way. It shouldn't fix the temperature, however.
Applied B's idea, but didn't test yet. I'm not into the mood of playing flash games for two straight hours today.

Poor performance and voltage fluctuation.
I'm running two 280x in crossfire which I upgraded from two 6970's. When I'm playing DayZ my FPS never go above 30 FPS. With my 6970's I was well into the 70's. I never changed my video settings when I went from the 6970's to the 280X's. For the most part I have a lot of the graphics low or disabled. Borderlands 2 is a nightmare on the 280X. I drop down into 10 fps area and this has never happened with on my 6970's.
During games my core voltage fluctuates between 500mhz and 1020mhz during game play. I have ULPS disable as well.
My power supply is an Antec HCG-900.
Happened on all these drivers 14.4, 14.6 Beta, and 14.6 RC (currently installed).jwcxz wrote:Have you looked at your process table for any program with abnormal CPU usage?

Performance issues in bootcamp with Passmark benchmark test
I wonder if anyone can shed some light on this
I've got a Win XP 32bit SP3 installed on bootcamp. When i test this using the passmark benchmark test (latest version on a 30 day trial). I get poor CPU performance. I am running a 2.53 13" MacBook Pro. I can compare the results with other peoples results from the passmark database, by same CPU and also by other macbooks.
My scores are nearly half what other similar macbooks are showing in CPU Math, which is quite a difference.
So i wonder what's up, and how can i check it further? Half sounds like only one CPU running.
I've compared VMFusion and Bootcamp as well and there's not much in them, both results are showing around half the performance. (This is Fusion running the bootcamp install. A free windows install in Fusion shows slightly better results but not that much)
Any pointers or help would be great, for example is there some way under OS X i can check the performance of the macbook as a baseline?
Is there something i've not done whilst installing Win XP through book camp?
thanks in advance!

Safari hangs and poor performance in MBPR (Mid 2012)
Safari hangs and poor performance in MBPR (Mid 2012)? OS X 10.10.2 is up to date
Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
Back up all data before making any changes.
Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
If your browser is Safari, then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. If the Downloads button (with the icon of a downward-pointing arrow) is showing in the toolbar, click it and then click Clear in the box that appears. The download history will be removed. Any change?
If you're running OS X 10.9 or later, select the Advanced tab in the Preferences window and uncheck the box marked
Stop plug-ins to save power
Any change?
Quit and relaunch the browser. Any change?
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
If Parental Controls is active for any user, please turn it off and test. Any change?
If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
Follow the instructions in this support article. Any change?
Open the iCloud preference pane and uncheck the box marked Photos, if it's checked. Any change?
Are there any other devices on the same network that can browse the Web, and are they affected?
If you can test Safari on another network, is it the same there?
If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference? -
Poor performance and high number of gets on seemingly simple insert/select

exe #2 : elapsed = 6.34s, query = 24272, current = 151, rows = 25
If I run just the select portion of the statement, using bind values from exe #2, I get small number of gets (< 10), and < 0.1 secs elapsed.
If I make the insert into an empty, non-partitioned table, I get :
call count cpu elapsed disk query current rows

This problem is part of testing of a database upgrade and country go-live. On a 10.2.0.3 test system (non-RAC), the same insert/select - using the real WF_Item_Attributes_Value table takes :
call count cpu elapsed disk query current rows
Parse 1 0.00 0.00 0 0 0 0

total 2 0.00 0.10 10 27 136 25So I'm struggling to understand why the performance on the 10.2.0.4 RAC system is so much worse for this query, and why it's doing so many gets. Suggestions, thoughts, ideas welcomed.
I've verified system level things - CPUs weren't/aren't max'd out, no significant paging/swapping activity, run queue not long. AWR report for the time period shows nothing unusual.
further info on the objects concerned:
query source table :
WF_Item_Attributes_PK : unique index on Item_Type, Name. Index has 144 blocks, non-partitioned
WF_Item_Attributes tbl : non-partitioned, 160 blocks
insert destination table:
WF_Item_Attribute_Values:
range partitioned on Item_Type, and hash sub-partitioned on Item_Key
both executions of the insert hit the partition with the most data : 127,691 blocks total ; 8 sub-partitions with 15,896 to 16,055 blocks per sub-partition.
WF_Item_Attribute_Values_PK : unique index on columns Item_Type, Item_Key, Name. Range/hash partitioned as per table.
Bind values:
exe #1 : Item_Type (:B1) = OEOH, Item_Key (:B2) = 1048671
exe #2 : Item_Type (:B1) = OEOL, Item_Key (:B2) = 4253168
number of rows in WF_Item_Attribute_Values for Item_Type = OEOH : 1132587
number of rows in WF_Item_Attribute_Values for Item_Type = OEOL : 18763670
The non-RAC 10.2.0.3 test system (clone of Production from last night) has higher row counts for these 2.
thanks and regards
Ivanhi Sven,
Thanks for your input.
1) I guess so, but I haven't lifted the lid to delve inside the form as to which one. I don't think it's the cause though, as I got poor performance running the insert statement with my own value (same statement, using my own bind value).
2) In every execution plan I've seen, checked, re-checked, it uses a range scan on the primary key. It is the most efficient I think, but the source table is small in any case - table 160 blocks, PK index 144 blocks. So I think it's the partitioned destination table that's the problem - but we only see this issue on the 10.2.0.4 pre-production (RAC) system. The 10.2.0.3 (RAC) Production system doesn't have it. This is why it's so puzzling to me - the source table read is fast, and does few gets.
3) table storage details below - the Item_Types being used were 'OEOH' (fast execution) and 'OEOL' (slow execution). Both hit partition WF_ITEM49, hence I've only expanded the subpartition info for that one (there are over 600 sub-partitions).
