  • PF usage way too high

    Shortly after installing SBS 2003 PE, fully patching it I noticed that the PF grew, and, grew, and continued to grow until it is slowing things down to a crawl. It is at 2.8GB currently. I have 2GB of RAM installed on a new Dell Xeon PE1900. We are not using exchange yet but have found the machine getting progressively very slow. Only 5 users, one v.small db (foxpro), and isa server.

    task mgr has this to say:

    PF usage: 2.81 GB
    cpu usage: 0%
    handles: 38572
    threads: 1354
    processes: 95

    System cache: 226052

    K Memory

    paged: 58232
    nonpaged: 43696

    Network load is <1% on either nic

    I get the following error:

    Allocated Memory 02/03/2007 12:45 AM 1
    A large amount of memory is committed to applications and processes. Consistently high memory usage can cause performance problems.

    To determine which processes and applications are using the most memory, use Task Manager. Monitor the activity of these resources over a few days. If they continue to use a high level of memory and are less critical processes or services, try stopping and then restarting them.

    You can disable this alert or change its threshold by using the Change Alert Notifications task in the Server Management Monitoring and Reporting taskpad.

    Can someone point me in the right direction???Please???

    Go back to task manager. Click on the processes tab and twice on the "Mem Usage"column header. This sorts the processes according to the most memory used to the least memory used. Which process is using the most memory? Is it SQLServer or SVCHost? If SQL server, what are you running in that process? SVCHost is a more generic process and to find out what is causing it to eat up memory you need to open a command line and run tasklist /SVC to see the actual processes running inside svchost.
    Having said all that, you usually find that it is normal for SBS to overrun its mamory size without any undue effect. Also that performance alert is pretty standard as you have not run any benchmarking to get that alert calibrated for your system.

      Hi Starbuck1 ~ that PF file really doesn't look that high. The sqlserv process seem seems high. There are some scripts that can set it to a more reaaonable level. Here are some articles ~
