Optimizing Page File

It's just been my experience with folks who think they don't need a page file. If you really look into how Windows allocates memory, just because you have 2Gb of system ram doesn't mean your PF isn't being used. At any given time, with F@H x 2 running and a few FF windows open, I'm using 500Mb of my 4092 page file.

Each program is given the same amount of ram. As an example, say that the OS kernel sets aside a 1Gb chunk of physical ram for itself and then a 512Mb chunk is allocated to each program. EACH program running is using it's own 512Mb chunk. It may not be using all of it at any given time, but it will want all of it if it decides to kick it up a notch, say your virus scanner. If you've set your page file too small, or hacked your registry to not use one at all, then your CPU starts being told by your OS to process this chunk, then that chunk, then the OS's chunk, and then back to the first chunk, all the while having to clear out Ram for each processing chore to make room for the program that's up next. You will, more than likely, slow your computer down by making the page file too small or by hacking it so it's not even there as each program now has no where to put the temporary files that are low priority. Instead, all the data is treated as high priority traffic, choking your system.

That's a very generalized and dumbed down version of what the page file actually does. Windows use of the PF is actually much more complex than that and I'm not sure I understand everything it does and how integrated it actually is in the OS's duties. But I do know enough to keep it set to at least twice my 2Gb of installed Ram. By making it a static figure in the PF options, I'm less likely to have a fragmented PF area on my hard drive. But you will never see me recommending anyone disable it.

As far as servers go, they are even more susceptible to system slow downs from a mismanaged PF. Each workstation is running its own instances of programs. If there's 16Gb of server memory for 128 workstations, and each work station is concurrently using 3-5 programs each, you can quickly kill the servers performance by not having a properly set and managed page file.

BLASPHEMY!

lol I never knew that, thanks for showing me the light!
