Windows2003: high swap file usage with 1GB RAM

    Hi,


    I have a customer running SBS2003 Standard SP1 on a Proliant ML350 G3, 3GHz,
    1GB RAM, 2x72GB SCSI RAID 1.
    The pagefile size is set to minimum & maximum 1536MB. It's on the C: drive.

    The users (just 5 in total) were complaining that the system was very slow.
    I ran "performance monitor" and noticed the following:
    Memory \ Available MB: 618 MB
    Paging File Usage \ %: 70 %
    Cache \ Data Map Hits : close to 100%
    Average disk queue length is close to 0, processor time about 5%,
    Interrupts/sec are about 200/sec.

    In task manager, I see Commit charge is 1400MB / 2470MB. No single process
    is using more than 50MB, but there are about 100 running (most resource
    intensive: SBS SQL monitoring, SBS Sharepoint SQL, WSUS, symantec AV,
    Exchange)

    If I understand this correctly, 70% of the pagefile (or 1075MB) is in use.
    Thus, it appears to me only 1400 - 1075 = 325MB is in use by the real
    physical system RAM.
    Can I somehow force it to use the system ram first?


    thx

    David

    I would not consider this enough ram for a server. Ram is cheap with all
    things considered. Min would be 2gig. I routinely max out to 4gig for my
    systems.
    This is not where the slowness is coming from imo. Are these SATA drives?
    How is the network setup? 100mb switch/nics for all? Everyone connecting at
    100mb? What are they doing when they report slowness?

    Off the top I would add ram and two drives mirrored for the data so you can
    breakup the disk io which will improve disk performance.
