    So, pardon my ignorance...

    What exactly does a pagefile DO? I figure the larger I make my pagefile max, the better performance I'll get.

    Is this true? How come?

    Thanks.

    this is as good a non tech discription as you can find

    as far as making it the max, once the pagefile is the right size, increasing the size will not give you benenfit.

    a great setting is 2x ram, leave expansion enabled to what ever xp lets you make it, and you should be fine

    I also found this microsft document, originally written for nt...later, microsoft recognized that pagefiles too small were causing great performance problems, and therefore, set the default pagefile bigger in xp...this is very important for everyone, especially those who think a small pagefile is a good idea...xp is by design made to perform with a big pagefile...here is the exact qoute from microsofr, as far as making a pagefile too big, versus too small in the nt kernal;

    "...A pagefile that's set too small can lead to overactive disk swapping, or "disk thrashing." The only real drawback with a relatively large swapfile is that you might not have as much disk space available for other uses as you would if you'd followed the pagefile setup recommendations."...

    so, obviously, back when nt first appeared, harddrive space was a rare commodity, and ms was trying to conserve same, as report to us, absolutely counterproductive when harddrive space is not an issue...in other words, you can make the pf large, but never ever make the pf smaller then the default.

    the default in xp, is NO LESS THEN 1.5 RAM, WITH EXPANSION ENABLED TO 3X THE 1.5 FIGURE, ( this is the default)

    Page file

    For Page file ,read "virtual memory"
    multiply your Ram memory by 2 for large amounts and 2.5 for small.
    Ie, 256 Mb Ram would need page file of 512 mb , see system properties / advanced /performance and set one value in the least used partition for max performance.

    For most people the first encounter with the pagefile is when XP runs out of virtual memory.

    The size of the pagefile, is really dependant on the software you use & how you use it.

    A little bit of photo editing puts you in the *Power users* bracket where a 2.5 x RAM pagefile might not be enough

    my tip for day
    *don't disable balloon tips*
    some of the messages are actually useful :)

    great post, 2z

    the settings you are using might be enough, but they might not as well...it is very important for users to make sure expansion is still enabled when you set your pagefile.

    it is a good idea to increase the initial minimum to more then the initial minimum default, as this cannot possibly be bad, but in so doing, you must make sure the operating system has the ability to provide more, if your needs so require

    also, it is most important to defrag the pagefile, after you make these adjustments...this is done most easily with the free pagefile defrag program posted on the free programs thread
