    The Server Performamnce report is showing W3PROXY - 4904 using 692 MB of
    memory and w3proxy - 2644 using 508 MB. Is this to be expected on a 30 user
    system with 4 GB of memory?
    Thanks

  2. Hi Chris,

    Thank you for posting here!

    I understand the problem is w3proxy.exe took high memory usage. If I
    misunderstood your concern, please don't hesitate to let me know.

    By default the Web Proxy will take 50% of physical memory as the web cache.
    You can lower the percentage (such as 20%). Please refer to the following
    KB:

    Percentage of Free Memory to Use for Caching" Means Percentage of Physical
    Memory
    http://support.microsoft.com/?id=322991

    If the problem persists, I think it should be a performance issue. And I'd
    like to provide the following info for your reference:

    Info 1.

    Such issue may caused by anti-virus real-time protection (such as Norton
    Anti-Virus). If you would, please try:

    1. Make C:\Program Files\Microsoft ISA Server folder as an exclusive folder
    for the Real-time protection.
    2. Disable AV real-time protection.
    3. Temporary uninstall Anti-virus software.

    Info 2.

    I noticed that if you've installed SurfControl, it will cause such issue.
    To solve the problem, I recommend you to contact SurfControl and obtain a
    newer version.

    I hope the above info helps and I look forward to your update.

    Thanks Bill
    It will be the first thing you mentioned because we do not use an active
    anti-virus on the server, the one we use Sophos is set to scann the data
    files only. We do not use SurfControl either.
    On the point of caching I wonder if IO should have much of a cache at all
    given that we use broadband?
    Thanks

    Hi Bill
    It looks like the default is 50% of the physical memory, wow! does it really
    need that much and if I reduce it how much is sensible? I think that other
    services make use of it don't they?
    We have the cache set to 100MB (on the disk) but I had not gone near the
    advanced settings. Any advice geatly appreciated

  5. Hi Theo,

    Thank you for posting back.

    Actually, ISA's Web Proxy service is designed to cache web objects to
    accelerate the web site access. However, this may also decrease the server
    performance when it takes half of the RAM (by default) to store the web
    objects.

    Since there're many components installed on the SBS server, a best practice
    is to set the memory percentage to 10% to 20%.

    If you have further questions, please feel free to let me know.
