[SOLVED] [QEMU] Improve graphics performance/resolution

Hi,
I use qemu's kvm feature and successfuly installed Windows 7 in it.
Everything works quite well except the graphics performance being very poor.
When I move the cursor it starts flickering ('lagging') and I can't set the resolution fitting my laptop screen with a native resolution of 1366x768. (So currently using 1024x768 in the VM)
I start qemu with -vga vmware.
command I use for starting qemu:
qemu-system-x86_64 -enable-kvm -machine type=pc,accel=kvm -cpu host -vga vmware -full-screen -k de -usb -usbdevice tablet -m 3072 /path/to/image.qcow2
Is there a way to fix this??

Finally got it working now, performance is surprisingly good!!!
I used to have Windows 7 Home Premium, then I discovered you cannot remote-connect to Home Prem as this version lacks that feature
So I got me Ultimate 64bit and it works.
I start the qemu vm with:
qemu-system-x86_64 -enable-kvm -machine type=pc,accel=kvm -cpu host -nographic -k de -usb -m 4096 -net nic -net user,hostfwd=tcp::3389-:3389 /home/kanikuly/Pictures/ISO/Win7Ult64Bit.qcow2
and rdesktop with:
rdesktop -g 100% -E -D -K -P -f -z -x b -r sound:off -a 32 -u *** -p *** localhost

Improving graphics performance in DIAdem 11.0 Report?

Dear Forum,
when working on a Report layout, the poor graphic performance of DIAdem is a real problem for me.
For example, many diagrams with lots of data are on one page. One opens the proficiencies of one of the diagrams and changes e.g. the curves color or whatever and closes the dialog window. After this, the whole Report page is refreshed - wich takes up to one minute, depending on the amount of data displayed.
The strange thing is, when I close the given dialog window, and while the report page is being refreshed sent DIAdem to the taskbar and open any other application window, the process of refreshing the screen takes only 1 second instead of 30 seconds.
The question is: Is there a tweak to improve the speed how DIAdem refreshes the report page? Or is there any workaround other than switching applications during refreshing?
Thanks a lot.
Greetings from Germany
Oliver

Hello Oliver,
The easiest way to speed up the graphics performance in Report with large data files (or 3D graphs with lots of nodes) is to turn off the "Data Layer" (German: "Datenebene") in the "View" menu (German: "Ansicht").
That function basically turns off the display of all data in Report, but retains the axis systems, texts, etc., so you can still move them, place them and edit them without having to guess sizes. Once you're done with the report, simply turn the data layer back on and you're ready to create a PDF, print or save the result as an image file (JPG, BMB, etc.).
I think the performance difference you described (1 vs. 30 seconds) is due to the fact that once DIAdem has drawn a page, it retains an image in memory and will simply draw that image when you bring DIAdem to the foreground (or maximize it). After any edits you make to the report (e.g. change the color of a graph), DIAdem redraws the complete page from scratch, which takes much longer then just re-displaying an image that has already been drawn previously. Someone from the DIAdem R&D team could probably do a better job explaining this, but I think this is the explanation for the time difference in drawing.
Anyway, the "Data Layer" trick should hopefully solve your problem, let us know if that works for you.

How best to improve graphics performance on RDS host servers??

We have a small RDS farm running on Windows Server 2012 R2.
All the RDS hosts and related servers are virtual servers running on vSphere 5.5 (hardware version 8 if that makes any difference).
I've seen various articles about configuring RemoteFX in Group Policy, but they are confusing.
I'm not asking about improving things like watching YouTube videos etc., I'm asking about improving graphics in general, like screen redraws and displaying mouse movements, keystrokes, etc.
What are the best things to do to improve these things within an RDS farm??
I will try increasing the video RAM within the host servers' VM settings but this is a guess, and these hosts are logged into by multiple users over VPN connections...
Thank you, Tom

This is what I'm talking about wrt MTU on the central SonicWall:
http://carltonit.wordpress.com/2013/08/09/how-to-optimize-bandwidth-on-sonicwall-nsa-2400/ -- see the ping command for figuring out the best MTU, then configure it on the WAN interface, advanced settings
http://www.firewalls.com/blog/sonicwall-throughput/
Can change MTU on central SonicWall, it's already been configured in the SonicWall 3500 in my building (1468) but I can't change all the other places (3 other agencies) that touch the central servers, they all use different ISPs and firewalls and routers
etc.
However knowing about MTU is a good thing.
Checking network usage etc. -- I'm usually not with the person(s) when they say things are "slow," I usually find out 'after the fact' or through someone else, sigh...
I'll work on MTU over the weekend...
Thank you, Tom

Improving Graphical Performance in OS X 10.5.6

Hey, I'm new here. Just entered the Mac universe for the first time with a MBP 2.4 ghz (2GB RAM, 250 GB HD (5400)) I went this route because I wanted a Mac that I could also game on but I've been disappointed with the results so far. I've tried running various demos of games that were designed for OSX (Doom 3, Halo, etc.) but I haven't had very good results. I run the games at around 1024 x 768 but they're really choppy (15-30 fps depending.) What am I doing wrong?
I changed the setting for performance > battery life but only see very little performance gain. I know that I just have a stock MBP but benchmarks led me to believe that this hardware would be more than suitable to games, especially one that are 5+ years old. Looking at other info on the net, I see that the 9600GT is more powerful than the Xbox 360's graphics chip which has me even more puzzled (9 or 10 gigatexels vs 8) I know that this is a computer like any PC and that games aren't going to be fully optimized to run better than the 360. It's just the nature of having programs that were designed to run on various processor, ram, etc setups.
Is there some additional panel I can access to better control my resources? Are there any resources available online that talk about how to optimize an MBP for gaming?
I searched the net using all sorts of key words but have come across nothing but glowing praises of the MBP's ability to tear it up on the graphics circuit. How is it that some people are even running Crysis on higher end MBP's? Your help would be much appreciated!

chris120,
The games that you mentioned (Halo, Doom 3) were released for OS X prior to the advent of Intel Macs. They were ported to PPC. After the Intel Macs came out, both games were updated to "universal binaries."
UB apps contain PPC code for running on earlier Macs, and Intel code for running on all new Macs. Some games, like C&C 3 were ported to OS X by wrapping them up in the Cider virtual machine, but this was after the release of Intel Macs. These games will only run on an Intel Mac.
Almost all games get some type of updates that optimize them, but that's not the issue here. Rather, we're talking about games that were originally ported to an entirely different processor architecture. This is no different than every other app that existed prior to the release of Intel Macs; all of these PPC apps run perfectly fine (most of the time) in Rosetta, which translates the code on the fly. However, the additional overhead needed for this is critical in the case of games. PPC games just do not run at all well in Rosetta.
When you see a game you think you'd like, make sure that it is a "universal binary" version, or Intel only. This will insure it will run well on your Intel Mac, without having to scour the web for the UB updates for it.

Improving Video/Graphics Performance

Okay, so one cannot upgrade one's iMac graphics card. Any other strategies to improve video performance? I have done the obvious like closing all other apps and maxing out RAM (4GB).

Thanks Dan but maybe I didn't make myself clear. What I'm interested in is whether or not one can expect a noticeable difference in video graphics performance between a 20" Cinema Display and a 23" Cinema Display, when connected to a Mac Mini Core Duo.

[SOLVED] Graphics performance on AOA 150 netbook and composition

Hello everyone.
First of all, I'm unsure is this post a bug report, a call for a help or a "how to". :-)
I'm using Arch on this netbook for 2 years now and I have to admit, that there is constant graphical performance slowdown with each version of xorg and xf86-video-intel increment (graphical controller is Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)). When I just had installed Arch, I'd had about 600 fps with glxgears (yes, I know, that glxgears is not a benchmark, but it's affected by all the same lags as overall graphical subsystem). As of few upgrades, fps became ~300. Then, when vsync was made necessary by Intel, I'd had ~60 fps. Now performance of graphical subsystem is extremely low -- ~25-30 fps. This slowdown affects both 3D and 2D, the gears in glxgears are rotating with pauses. The most interesting thing is the mouse activity influence. When I move the mouse during the test, fps increases. If I'll move mouse constantly during the test, I'll get ~60 fps.
For this two years I'd used different window managers and desktop environments in different combinations, but result was the same: desktop composition had always decreased fps rate. But with cairo-compmgr I'd got very strange result. If it's active, fps is constantly ~60 and gears are moving smoothly, no matters how I move the mouse. As for me, the main question is why is this happens and how this result can be achieved without any composition (cairo-compmgr is quiet buggy for now).
As of practical usage, now I use gnome3 in legacy mode (because of lags under mutter) with cairo-compmgr running, all it's visual effects are turned off. Fps is ~60.

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 -

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...

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?

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...

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.

How about the Graphic Performance?

Hello all!
May someone can help me to get that clarified ...
I have a MacMini with Thunderbolt connection. Latley I started to use RC Flight simulator which challenges the video card of my MacMini pretty much.
How about a Thunderbolt Display? Will TB just "substitute" my current HDMI-Connection or will some computing power be "outsourced" to the display? In other words: will the graphic performance of my MacMini improve using a TB-Display or does it stay the same because the build in video card is still "in charge"?
Thx for your help!

No question the Thunderbolt is without doubt a fantastic display, however to answer your question I'm personally experiencing a performance drop (see my very recent thread in this forum).
One of my reasons for finally getting the Thunderbolt Display was to enjoy some proper gaming on a big screen for 3D games both within OS X and Bootcamp. Even when I match my MacBook Pro 17" unibody's (early 2011) top resolution with the Thunderbolt Display for a like for like comparison, I get a performance drop which I was hoping would never happen. I was hoping that with the MacBook Pro in closed 'clamshell' and thus the MacBook Pro switching it's own display 'off' and presumably diverting all of the GPU's performance power straight to the Thunderbolt Display via it's direct fast Thunderbolt bus; that it would at the very very least match the performance when using the MacBook Pro's own display, but currently I have to choose the 'very low' graphics setting on some games to maintain a decent frame-rate for smooth game play.
Mybe this is not a permanent Thunderbolt Display problem/fault and might be resolved at some point by means of a software, display driver or display/thunderbolt/GPU firmware update. If that be the case then I'll know there's hope at the end of the tunnel. Understandably I wasn't expecting my MacBook Pro 17" early 2011 to perform miracles with it's graphics performance anyhow, but it's 1GB Graphics adapter isn't all that bad either and is a half decent card that can give acceptable results. But If you where to match the resolution of the Thunderbolt Display to that of the MacBook Pro for comparison for yourself and then run a 3D game like say 'Dirt 2', you will soon realise there are slight performance issues; unless of course I'm doing something wrong.
Here's hoping this may only be a temporary drawback for the Thunderbolt Display with 3D applications/gaming.

Improving G5 performance

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,
Chris

Thank 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

10.6.7 Serious Graphics Performance Trouble

Hello.
Today I updated my MacBook from 10.6.5 to 10.6.7 using the Combo Updater as well as doing a few other system updates. Already since 10.6.4 my graphics performance had worsened considerably as I had what appeared to be overheat trouble with the GPU after 15 minutes of gaming at most, making the FPS drop from 60 to 15 randomly.
With the update to 10.6.7 I now can't even exceed 20 frames per second in the first place anymore. Games in which the error occurs: FlightGear 2.0.0 pre3, Redline 1.0.5
Apart from in games, my Mac generally gets "stuck" particularly often, no matter if it's supposed to move a 15 MB video file into trash or if I'm editing a couple of images with Gimp.
What could cause this and how could the error be solved?
Hardware:
MacBook Aluminium Unibody 13"
Intel Core 2 Duo 2.0 Ghz
2 GB DDR3-RAM
NVIDIA GeForce 9400M 256 MB (shared)

Found this on another discussion forum.
These are the .kext and other files which needs to be replaced. You should back up before you install any packages:
/System/Library/Extensions/GeForce.kext
/System/Library/Extensions/GeForce7xxxGLDriver.bundle
/System/Library/Extensions/GeForceGA.plugin
/System/Library/Extensions/GeForceGLDriver.bundle
/System/Library/Extensions/GeForceVADriver.bundle
/System/Library/Extensions/NVDAGF100Hal.kext (if it exists)
/System/Library/Extensions/NVDANV40Hal.kext
/System/Library/Extensions/NVDANV50Hal.kext
/System/Library/Extensions/NVDAResman.kext
/System/Library/Extensions/NVSMU.kext
You can get around the hardware verification check by right-clicking the .mpkg and selecting "Show Package Contents".
In the "Contents" folder that's shown, navigate to "Packages".
Inside that you'll see three .pkg files: Display Driver.pkg, OpenGL Driver.pkg, and Video Driver.pkg.
Each of these hopefully installs without a hardware verification check.
There is another solion given by edit setup checking algorithm:
Simply locate "distribution.dist" inside driver package,
then delete part of program with "unsupported_title" and "unsupported_message" strings, save and install.

CS6- Sluggish Graphics performance

Hi;
I just installed Photoshop CS6 on a Windows 7 64-Bit system with an ATI 5870 Graphics card and the latest ATI 12.4 drivers. Graphics performance seems to be noticeably worse than CS4 that I upgraded from.
   The very first thing I tried was pasting a copy of an open Desktop Window (Alt-Printscreen) into Photoshop (File/New then paste). Then I simply alternated between 'Fit on screen' and 'Actual Pixels' to watch the magnification change.
'Zooming' performance seems noticeably slower/jerkier than with CS4.
I played around with the 'performance' options and I discovered that the fastest setup seems to be when I go to Graphics Processor Setting and uncheck the 'Use Graphics processor' box (It was checked by default) . Then, things seem pretty snappy. The zoom doesn't seem to have much of any 'animation' as it changes level.
The next quickest seems to be when I leave the 'Use Graphics processor' box checked, but change the 'Advanced settings'/Drawing Mode to 'Basic' (down from the default 'Advanced').
Here, the zoom seems to be smooth, but seems to have a little bit of an 'animated' appearance as it is growing or shrinking (as it changes the zoom level). The worst performance is the default drawing mode of 'Advanced'.
Does anyone else see this issue with CS6 and ATI graphics? Is it expected to have to turn down the graphics setting to get improved performance?
The ATI 5870 isn't too shabby of a video card, and I expected better with CS6.
The 64-Bit version speed doesn't seem any different, although the Graphics setting for 'Use OpenCL' is checked in 64-bit version of CS6
My CPU is an Intel I980X (3.33 GHz) 6-Core system, in case that helps.
   Thanks;
     -Greg

I rolled back the drivers to the AMD 12.2 Catalyst video driver version and things do seem much improved.
With only limited testing so far, things now appear to be (mostly) at least as fast as without the 'Use graphics card' option checked.
I say mostly because with the graphics card being used, I now see some short 'delays' in some actions that aren't there without it. For example, starting CS6 and then doing a 'new' followed by 'paste' seems to have a little delay in there that's not present without the use graphics card option. (Maybe it's initializing the card, I don't know).
It seems like the graphical effects for things like 'Iris Blur' look fancier with the graphics card being used, but so far it's not clear if they are actually any faster/more responsive. 'liquefy' looks very smooth with or without the 'use graphics card' option.
At least performance is no longer absolutely horrible (using the 'Graphics acceleration')... . I'll have to try it out some more.
Thanks!

Improving Report Performance

Hi HTMLDB Team,
I need some of the undocumented HTMLDB information to improve the performance of the Reports, which will be of useful to every one.
I have a Customer table, which has 1 Million records in it. It has the following columns:
First Name, Last Name, Customer ID, State.
I have a Report Region (PL SQL Block returning the Query), which directly picks up records from this table.
User can filter Customer Records by any of the above-mentioned column.
With out any sorting I am getting the response in 2 seconds.
But If I put Sort on any of these columns my response time goes to 1 min.
I have index on all the columns too.
If the user applies any filter like "State=NY" or "First Name=Balaji" I am getting the response in 2-3 seconds.
Now I want to keep the Report Response time within 2-3 seconds. (Without any filter condition and sorting on some column say "First Name".)
In order to achieve this I want to add dynamically some filter conditions to the original query. when there are no filter conditions specified by the user.
My approach is based on the assumption that user will be shown only the first 500 records of the query results (This is the normal HTML DB report behavior and I don't want to increase the Report Region max count beyond 500)
My Original Report region query is
SELECT * FROM CUSTOMER ORDER BY FIRST_NAME. -- It is taking 1 minute to returns all 1 million records out of which we are showing only the first 500 records.
If I rewrite this query as
SELECT * FROM CUSTOMER WHERE FIRST_NAME < 'B' ORDER BY FIRST_NAME. -- Takes 2 seconds and returns more than 1000 records.
Now I can use the second query to show the records if the user did not specify any filters and he will be shown only the first 500 records.
Now my issue is if the user changes the Sort Order to "Last Name" then the above query will not work and I need to change my query as
SELECT * FROM CUSTOMER WHERE LAST_NAME < 'B' ORDER BY LAST_NAME.
Similarly if the user selects State as the Sort Order
SELECT * FROM CUSTOMER WHERE STATE="AK" -- Will definitely give me > 500 records.
Also I need to consider whether the user is sorting in Ascending or Descending order too.
From where can I get this Report Sort Order information in HTML DB?
If you can provide this information, it will be of great use to all HTML DB folks.

Hi!
What exactly did you find at mentioned link regarding report performance ... it is not about performance issues for reports ... id is about navigation from a report row to a page.
Please, can you tell more exactly what thing solved your solution?
I have the same situation, a query runing about 1 second dirrectly on the database from SQL Developer, but from APEX page it takes about 55 seconds.
Thank you.

Improving VLC performance

Hi!
Im playing some mkv movie with vlc
This movie is 24 Gb (1080p) and is being played through an integrated 512 Mb nVidia video card, connected via HDMI to a 32'' TV......
This did not happen before, and the memory does not seem to be the problem here. (Although is one of the few movies i download that are this huge, i usually download 8 Gb ones, more or less...)
I post this pic showing gnome system monitor:
As you can see, the processor's resources are being used, as for my understanding, wrongly,,,,,, as one of the cores is at its 80% usage, the other one, remains 20%...... they never are used 100% - 100%,,,,,,
The system is a dual core 6000+ AMD processor, with 2 Gb RAM......
My point in this thread is: Is there any way on improving the system's performance without purchasing a new processor / more RAM / Better graphic card? or is my system outdated?
Any VLC's options that would tweak the video playback?
Thanks!!

Another option, would be reduce the mkv file myself, reencode it somehow, no? I have mkvtoolnix, but i dont quite know how to use it for this purpose.... i use it for embedding subtitles inside mkv files, but nothing else appart from this.....
Anyway, i prefer i juust improve the performance instead of reducing the file size.......

Need suggestions on improving the performance end to end

I referred following links and as many as 25 previous posts before posting this question.

I have some queries related to improving the performance of a scenario in my landscape.
Scenario : IDOC-SOAP (Synchronous with BPM)
The mapping is simple with 3 fld direct mapping.
Works grt with no problem in normal cases for one message transfer.
But initial load ( when we put it in new system, the scenario generates erros if we send more than 23 IDOCs at a time)
I have decided to perform the following to solve it.
/people/william.li/blog/2008/03/07/step-by-step-guide-in-processing-high-volume-messages-using-pi-71s-message-packaging
Will it help me because its a IDOC sync scenario.
What can I do to improve the performance of this scenario?
Please suggest me good suggestions to improve the performance
Please do list me out points that I have to perform (for a sync scenario with BPM) as I am already confused watching lots of blogs posts.
Nikhil.

do you think that the performance tuning that I mentioned in the link will hold good with sync scenarios?
i dont think so.....in this scenario the async mesg processing is made to wait
from the blog:
As you can see, for the 1st minute, all the messages are waiting to be processed. After 60 seconds,
the packages will be created and processed. There is no change to the monitoring of each of the
individual messages in SXI_MONITOR.
....but if you make a sync scenario wait....then probably you may run into the risk of blocking the Queues.......
If this is going to be in production then i would have been more careful...becoz firstly it is BPM....then synchronous BPM.....then a processing wait......normally do not try to make the BPM processing wait...my small suggestion
