Hmmmmmmm, I'm starting to think these settings are "feel good" settings. I set them each to 2, to 0 with Superfetch on, disabled, whatever. No matter how I set them it uses nearly half my ram as Standby. Not only that, but if I run no swap file, it pops up Out Of Memory dialog when I have 800 MB on Standby. It wants to see that swap file even if it only uses 90 MB of it. So I set it back to 3 each and turned Superfetch on. Gave it a one GB page file to make it happy!! Man it's really weird!!
When I get the Out Of Memory Dialog I just hit cancel since there's really 700 or 800 MB ram available. Really strange.
I just checked resource meter and it has me at 0 free memory but over a GB on Standby. Really crazy(and yes I know the theory of how prefetch works, but isn't it against the theory if it does it when it's shut off?)
edit: hmm, setting Superfetch to 2 made a big difference in Vista. But it looks like Windows 7 wants to prefetch no matter what. Trying it with the default 3 settings seems to be a bit snappier. It doesn't bog like Vista did with that setting. Guess I'll let it do what it wants.
