Windows Performance Analysis Tools

The Windows Performance Tools (WPT) Kit contains performance analysis tools. Windows Performance Tools are designed for analysis of a wide range of performance problems including application start times, boot issues, deferred procedure calls and interrupt activity (DPCs and ISRs), system responsiveness issues, application resource usage, and interrupt storms.

The Windows Performance Tools (WPT) is part of the Windows 8 SDK and the Windows Assessment and Deployment Kit. In this guide I'll use the Windows 8 SDK Installer to install the WPT.

Go to the download site of the SDK:

http://msdn.microsof...rdware/hh852363

and click on the button download to download the Webinstaller:



and store the installer on your HDD. Now run the setup and this screen shows up:



Click next and select the WPT from the list:



Click "Install" and the Setup downloads the required files.



and installs the WPT



After a reboot (required to add the WPT folder to the PATH variable to run the tools from every place) you are ready to follow my xperf guides here on msfn:

http://www.msfn.org/...howtopic=140264

1 tip: The setup stores the MSI files in the folder C:\Program Files (x86)\Windows Kits\8.0\Windows Performance Toolkit\Redistributables. The 32Bit version is named WPTx86-x86_en-us.msi, the 64Bit version is named WPTx64-x86_en-us.msi. The 3rd file (WPTarm-arm_en-us.msi) is needed for ARM based tablets/notebooks which run Windows RT.

You can use the MSI installer to avoid downloading the WPT after you reinstall Windows!

Does xperf only work for Windows 7 ?
I have windows XP and big issues with interrupts using 95% of my CPU on Windows XP. So I was trying to follow your instructions but somehow it doesn't work.
When I find the MSI file as per above and install, it tells me it has installed successfully. But then the xperf command doesn't seem to work...
thanks!

You don't really have to download the whole SDK to do this. Over at reboot.pro http://reboot.pro/13...__1#entry113919 they've presented an excellent way to remotely mount an ISO (http://www.microsoft...&displaylang=en) through HTTPDisk and get just what you need at the moment.

[MagicAndre1981]

install WPT on Vista/7 and copy the folder to XP and run the trace there.

AM having a network related DPC I recorded 2 files, but forgot to change the name on the second, so thinking both of these might be the same, here is my link, and seems to be with newzleecher bad, and firefox minor, though newsleecher sees 4.4MB/s, though sometimes 2.5-3.5 with DPC's, and firefox was only d/ling at 850KB/s-1.2MB/s. I have updated my Realtek drivers for NIC. I can list other performance tests, and monitors. Seems the trouble spawned while using MSI updater and AISuiteII updater. If I try to use AISuiteII updater I get a ASupio.sys BSOD, so haven't been using it. But seems that somehow from these updaters, I now have the mass CPU usage from d/ling. I really only see about 60%(newsleecher) and 40%(firefox). I have asus m599x evo(MB) AMD Phenom X4 805 OC'd to 3.26, and 16GB Corsair LP Vengeance 12800 @ 1732. MSI GTX550Ti VGU, and realtek OB NIC

please post inside the DPC/Interrupt topic next time.

Your driver of the Realtek is "Rt64win7.sys", "7.043.0321.2011 built by: WinDDK", but the latest version is 7.046:

And the realtek chips have no own CPu to do operations and the main CPu must do all work.

Hi

My installation of Windows Performance Tools Kit fails. What should I do? Here is the log file:SDKSetup_7.0.6918.0.log

[MagicAndre1981]

this is a good question.

do you see this file? You can also try to get the Visual Studio 2010 tool or try the Windows7.1 SDK:

I am installing the 7.046, in hopes that this fixes my error. Though one question to this is, that I also have a belkin usb wi-n and with the realtek driver disabled was still having the same error, so thinking this will not fix my problem, will post soon enough though

I still have the same problem, so this is not the source of it.

I dowloaded Visual studio 2010 tool and that installation succeeded. Dumb question but do I still have to install Windows 7.1 SDK?

no, If you have installed WPT you don't need to install the SDK any longer.

[MagicAndre1981]

*Update*

I've replaced the Windows 7 SDK link to the Windows 8 SDK link. Now you can use the guides on Windows 8, too if you have any issues with the new Windows.

MagicAndre1981:

from 2011 someone asks if it can be run in XP (but doesn't) and you state to install on Vista/7 and copy folder to XP. However, I do not have any way to install on Vista/7 because I'm still running MCE2005 (SP3). Is there another work around to run in XP? I'm running Process Explorer and DCP/interrupts are very high due to drivers or hardware (or both). Need a way to figure it out now before something fails.

Thank you for any help you can give.

[MagicAndre1981]

You can use UniversalExtractor to extract the MSI:

Hi. This works for Vista? I download the sdk installer, but it does not give me the check box for the WPT like it shows in your tutorial. Checked everything there and installed, but the still get the xbootmgr error.

[MagicAndre1981]

I haven't tried it on Vista with the new Win8 SDK. You can try the old WPT from the Win7 SDK:

Thanks, I will give that a try
