Why is PF usage so high
I have just increased the memory in my PC.
I noticed in task manager that you can monitor PF usage.
Please can someone explain why this value is so high.
I thought page file (swap file) was only used when you run out of physical RAM.
Having just increased from 256MB to 512MB, I am suprised to be using 200MB of page file.

- This might not be pertinent, but years ago when I was working on IBM main frame installations, whenever I executed a program, that program was read off the hard disk, then IMMEDIATELY written to the virtual memory. All subsequent references the the program software were made to the VM. Could that be what's happening here??

As I (roughly) understand it, Prefetch puts some app pages into VM for faster loading of the app; also, Windows XP loads much of itself on startup, first in RAM, then moves bits of itself to VM, to release RAM as you open apps.Hm, I forgot this one:
