    Unanswered: Memory Available Bytes

    I'm taking a look at a server to optimize it and need a better understanding of the Memory Available Bytes.

    If the graph is showing this @ 100 is that a good or bad thing.
    Articles are saying it shouldn't be below 4MB...
    Can anyone elaborate?

    thanks,
    Jonathan

    Look at Last, Average, Minimum, and Maximum of the counter. Of Course the average will show you the avg of available bytes, which (if you ran the counter for an hour or more) should be your guiding value. In order to see the true graphical representation of the counter, instead of it showing 100 on the graph, - change the Y scale. (edited) In Vista you can right-click on the scale and chose "Scale selected counter" when the counter is highlighted at the bottom of perfmon.

    It should not go below 10MB. But in general, this counter should always be above 5% of physical RAM on the box.
