    Running Windows 2008 Server SP1 64bit on a VM. The guest has 4GB RAM installed.

    If I look at Task Manager, it tells me approx 3.5 GB physical memory is being used.

    I launched Perfmon and checked the following two counters (figures in brackets for average:

    i. Commited Bytes : 2.5 GB
    ii. Pages Output/Sec: 0
    iii. Available Mbytes: 420

    I'm confused :)

    According to the above, I'm not paging as the Commited Bytes is less than the available RAM. Pages Output/sec confirms this.

    But then why do I only have 400MB RAM spare? Shouldn't this be much more? To add to this, Task Manager says I have:

    Total: 4094

    Cached: 2935

    Free: 80

    Could someone confirm the best counter to use to see whether I really am running low on memory?
