PF Usage

[Kevin Simms]

What is "Page File Usage"? When you open your task bar
and look at performance what is PF Usage? Is it simply
RAM usage? What else is it telling you. I've never
gotten a straight answer.

Thanx, Kevin Simms

"The pagefile usage represents how much memory is set aside for the process
in the system paging file. When memory usage is too high, the virtual memory
manager pages selected memory to disk. When a thread needs a page that is
not in memory, the memory manager reloads it from the paging file."

Apparently, PageFile=Virtual memory

"The pagefile usage represents how much memory is set aside for the process

manager pages selected memory to disk. When a thread needs a page that is
not in memory, the memory manager reloads it from the paging file."

I got a gig of Corsair TwinX 3200LL-PT memory... why does XP still insist on
using 227 MB of PF memory?

It is a misleading number in XP. Read up at

It will be using some *potential* space there for potential use by
memory space that programs have asked to be allocated, but never used
(so there is no point in tying up RAM for them). Nothing will actually
be written to the file, and if the pages do come into use, they will be
created in actual RAM space See www.aumha.org/win5/a/xpvm.htm
