I had been using 256MB memory. A few days ago, I replaced it with 512MB
memory. But I'm using the same Windows installation.

When I was using 256MB, the size of page file was about 300MB and the
PF usage in the TaskManager hardly exceeded 200MB. Now it has 512MB ram
but the size of page file has been increased to about 700MB Should I
keep this large page file? I check PF usage at the TaskManager often
but I've never seen that it exceeds 300MB. I guess my physical memory
size is large enough for my everyday computing without page file. Is
there any performance degradation if I set the page file size to 0 or
smaller size?

Yes.

It's probably 768MB. By default Windows makes the minimum 1.5 times the
amount of RAM you have.

You don't need that much, and could decrease the minimum to 200MB or so;
leave the maximum high just in case you ever need more.

Thanks for your advice! I set it to 256MB (initial) ~ 1024MB (maximum)
with 'custom size'.

That's perfectly normal. By design, Windows uses as much physical
memory as it available to it. When memory is needed by an application,
Windows will release the necessary amount. Remember: Unused RAM is
wasted RAM.



Yes. WinXP was designed and optimized to operate with a page file.
The simplest, and usually best, course of action is to allow Windows to
manage the page file.


Yes, there may well be, and some applications may not even work. For
your edification:
