    Hey guys, I just noticed pagefile.sys and hiberfil.sys are taking up like 20GB between them, do I really need a 12GB page file if when I have 12GB of ram installed? can I switch the page file off? what are the optimised settings for this bloody thing?

    I was going to say "Do your own googling" but I'll be slightly more helpful by pointing you towards MS's recommendations http://support.microsoft.com/kb/889654 for 2003/XP.

    As mentioned page file size is related to the type of loads you put your machine under.

    Determining a more precise number is a matter of observing various metrics under various loads.

    Since most home users use their PC for wildly different functions its hard to know what a 'typical load' is.

    I would however agree that its highly unlikely you will ever need much of a pagefile if you have 12GB physical memory and you don't go out of your way to waste resources.

    You could turn off paging entirely, some people report this as a good move, however MS does not recommend this and certain crash dump functionality seems tied to having paging turned on.

    I'd therefore maybe put it down to a lower value say 2GB and see if you ever run out of paging space. If you are using a 64 bit OS you will need a pagefile slightly larger than physical memory for crashdumps to be generated.
