pagefile size
Posted by mc on November 24th, 2005


Hello
I've read that my pagefile could be reduced by placing a value of 1 in the
registry. What is the exact method of entering this value?
thanks mc

You are better off doing it the safe way. Open the properties page on "My
Computer". Select Advanced, then click "Settings" in the performance
section. Then select the Advanced tab. Click "Change" in the Virtual Memory
section. From there you can set the page file size, or even select no
pagefile (not recommended). You can also move the pagefile to another disk.

I wonder what a recommended PF size is?

On one forum I read 2x on another 2.5x based on total RAM available

See the article on Virtual Memory in Windows XP by the late Alex

The pagefile is used to compensate for the *lack* of sufficient RAM in
the machine to meet the total memory load being placed on it. More
RAM means less pagefile use and less RAM means more pagefile use.

Pagefile requirements are *inversely* related to the amount of
physical RAM, provided all other factors are held constant.

Websites that advocate pagefile settings based on a multiple of the
RAM quantity only serve to prove that the authors of those web pages
have no real knowledge of how memory management works in Windows XP
and therefore they should be totally disregarded. That includes any
such pages on the Microsoft web site.

Exception: If the computer is configured to produce a "Complete
memory dump" when a system failure class error occurs then the
pagefile size must be at least equal to the amount of installed RAM
because the pagefile is used to receive the memory dump content.

Good luck
