PF Usage

G'day guys

Could someone please explain what this means in words I can understand??

eg, if I have nothing opened and my CPU usage is ZERO then why is my PF usage anywhere between 250 and 450???

I tried HELP in Windows but no good....

Cheers

 

It may be proccesses or cache`d stuff maybe ?

 

Here's why:
We now have two types of memory; random access memory (RAM) and virtual memory, or the page file. The page file is created during the Windows XP installation and resides on the hard drive. Page files are measured in megabytes. The size of the page file is based on how much RAM is installed in the computer. By default, XP creates a page file which is 1.5 times the amount of installed RAM and places it on the hard drive where XP is installed. Other than plugging the RAM into the motherboard, there is little than can be done to alter its performance characteristics. The page file is a different story. Because it's located on a hard drive, it's subject to a number of factors that can hinder its performance.
