Limiting the System Cache is sometimes beneficial! Specially on 64 bit version of Windows. <\/p>\n
I had some problem after installing 8GB additional system RAM under Windown 2003 x64 server and disabling the page file \/ setting it to 1GB from 4GB. It seemd to use all the RAM for system cache (file cache) and displayed ‘virtual memory too low’ warnings once or twice. I mean I added 8GB RAM and decreased the paging file by 4GB (3GB) and I never had problems before so I should have been fine. +8 -3 = low memory? Somehow the math doesn’t add up.<\/p>\n
I found a lot of articles describing the same problem I had. (windows uses half of the memory for file caching)
\nThen I tried tweaking some settings.<\/p>\n
Registry settings: Session Manager\\Memory Management\\ I’m not sure if the System Cache info in Task manager is accurate or what does it exactly count. SysInternals Process Explorer displays differente value (equal to Performance monitor Memory\\Cache Bytes counter) for System Cache.<\/p>\n To reset the cache size use SysInternals CacheSet. or Microsoft Windows Dynamic Cache Service More info about memory management and system cache: Too Much Cache You may experience a decrease in overall system performance when you are copying files that are larger than approximately 500 MB in Windows Server 2003 SP1 or in Windows Server 2003 SP2 Things to consider before you enable System cache mode in Windows XP There are a lot of other good articles about Windows Memory Management, Performance Monitoring and I cannot list them all. http:\/\/blogs.technet.com\/b\/markrussinovich\/archive\/2008\/07\/21\/3092070.aspx<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Limiting the System Cache is sometimes beneficial!
