  • virtual memory grows up more than default size!

    hi every body
    my data16GB RAM base server has and has installed windows 2003 enterprise edition on it.
    i did set the minimum size of virtual memory about 2Gb and maximum about 4Gb
    but now i see the PF usage of this server reaches to 8.5 Gb! why?
    can anyone help me

    Virtual Memory is supposed to be managed by the OS - but if you insist on having manual values set, Microsoft reccomendations are to have it set to 1.5 times the amount of available RAM. For a 16Gb RAM system therefore you should set a manual size of 24Gb. (Min and max). Once again however, the proper way to do this is to set a system managed size and enter no limits yourself.

      System managed pagefile leads to excessive fragmentation. Do you really want 24 GBs of virtual ram? If that even occurs its either because your application has a memory leak or your system needs more RAM.

      I always set my pagefile to double my RAM up to 4 GBs, minimum and maximum.

      1 GB RAM = 2 GB pagefile
      2 GB RAM = 4 GB pagefile
      10 GB RAM = 4 GB pagefile
      100000 GB RAM = 4 GB pagefile

          So - it got really complicated; BUT

For business-critical servers where business processes require to server to capture physical memory dumps for analysis, the traditional model of the page file should be at least the size of physical ram plus 1 MB, or 1.5 times the default physical RAM.

            hi alinagoo

            i have the same issue
            8G of ram on server 2003 64 bit
            yet the pf usage is on 8G

            and like u it set on 2-4G

            is it a terminal server you having the issue on?
            in my case this is a ts so
            if a user log off the size of the pf is
            decrease with a 0.5-1G

              also want to point

              as i understand pg usage is not just the page file
              i mean, if u look at the page file location
              u will find the page file called pagefile.sys
              check its weight
              mine is 2.5G
