Help - Too Much I/O On XP Sp2

A PC can run perfectly for years then start to misbehave for no obvious reason, perhaps because numerous files have been upgraded in the background. Using the site is easy and fun. In this case it's a subversion server (running VisualSVN). The copy is from the cluster, using a SAN, to the other machine.

I checked and lsass.exe is running under: C:\\WINDOWS\System32\lsass.exe Back to top #4 Gator Girl Gator Girl Topic Starter Members 3 posts OFFLINE Local time:09:10 AM Posted 02 January 2008 - If during your test, you see the system file cache grows to overtake all of physical RAM, then you should use this service. Additionally the cache needs to share the kernel address space with other kernel resources, so your cache's working set won't even get up to 2 GB. Since most systems have more than 1 GB of physical RAM today, having the system cache working set consume physical RAM with read I/O is less likely.

Will there be a hotfix that addresses this? I've not seen any systems going under 80 ns, but not done performance work on DDR3 yet so it may be possible outside of cache. The APIs are only used to set limits on the System File Cache's working set.

After investigating for a number of days, using Task Manager and pulling up the I/O writes column, I found that lsass.exe is performing an unbelievable number of writes. It is difficult to provide 1:1 support through blog comments, if you need troubleshooting assistance you may want to open a support incident so that our engineers can assist you.] Reply That should give you nice graph. –Josip Medved Aug 18 '10 at 8:11 @Jawa: That is the way. :) –Josip Medved Aug 18 '10 at 8:12 Process https://blog.tatham.oddie.com.au/2007/07/28/strange-server-behavior-huge-io-other-count-for-csrssexe/ Whenever Iminimized my RDC window, it stopped requesting data and the I/O bytes graph was stagnant.As soon as I brought the RDC window back up and started interacting with it, the

The Dynamic Cache Service is one example of how to use these APIs, but there is a hard coded check for Windows 7 in the service. You read more about it here. Check out this post for more information: http://blogs.msdn.com/ntdebugging/archive/2007/10/10/the-memory-shell-game.aspx Also, if you think that the Dynamic Cache Service is not working, you can use the debug build and DebugView to see exactly I have set up a scheduled task to run setcache daily and have to see how it behaves from now on.

I can't figure out why im still having this problem… Darrin Leboeuf says: June 10, 2008 at 17:56 Thanks for the info… I have the same issue with csrss.exe getting HUGE In order to maintain the settings you’ll need to run the tool at least once per boot.

Just my 1 cent. Since these functions don’t exist on earlier versions of Windows, the SetCache.exe binary was compiled with the subsystem version set to 5.02, which prevents it from running on versions of Windows It doesn't actually seem to be causing a problem, it's just out of the ordinary. any says: June 28, 2010 at 23:10 Any solutions for this in 2010 ?

We are working on improving this experience in the next version of Windows. The box is a 1.8GHz Core2 Duo running Windows Server 2003 R2 Standard x64 Edition. share|improve this answer answered Aug 18 '10 at 7:56 Josip Medved 7,77111937 I'll try with ProcExplorer as it's already installed.

It defaults to 100MB instead of the original 1MB. [By default the sample code is hard coded to set the minimum to 100 MB, but not enforce it.

The changes are extensive and the risk of regression is far too high to backport to the current operating systems.] Reply ExchangeVigilantes.com says: September 7, 2008 at 8:40 am Excessive paging The sample code and included binaries are completely unsupported. The main reason for this is to repeatably retest the performance of an Analysis Services query on a completely cold system file cache (without server reboot). Ed [There are many design challenges for a general use operating system.

With default settings (no tweaks), Task Manager's Physical Memory Cached grows while Free goes to 0. although it is a high spec server, the high I/O being generated hampers the performance badly. One has 2 instances and the other is a cluster. Having a lot of cache is generally not a bad thing, but if it is at the expense of other processes it can be detrimental to system performance.

Following some suggestions in this post'scomments and on Googlethat this might be a virus, Edward suggested I fire up a copy of SysInternals Process Explorer on the server. We chose to implement this tuning option via API calls to allow setting the cache working set size dynamically.

Thanks again - finally some performance on this Server. SysInternals (which was bought by Microsoft) provides a much better utility: Process Explorer.
