Note several things:
1. The page file size has *no* effect on System Performance. A larger page
file lets you run more apps, but it doesn't make any program run faster.
2. Since the page file substitutes for real memory, when there isn't enough
RAM for everything you want to do, the larger the amount of RAM you have,
the *less* page file you need. Therefore all the "rules" that specify how
much page you file you should have as a multiple of system RAM are wrong.
That's true of 1.5X as well as of 2X
3. Having a page fie larger than you need it has no downside except that
it's a waste of disk space.
4. For most people, letting the system manage the page file size is fine,
but in general, if you want to set the page file size manually, you should
make the starting size small (100-200 MB or so) but let it expand to as big
as it needs to.
