You have plenty of RAM so you shouldn't see much of a performance hit, you probably won't notice any difference.

There will only be one large pagefile on E:. You can set the pagefile to the same size in both operating system... or to different sizes, it doesn't really matter, when you boot the operating system the Session Manager reads the pagefile settings information from the registry and creates the pagefile according to the information held in the registry so it doesn't matter what the other system in your multi-boot setup does, the other one will do its own thing when it boots. The small pagefile on the other partition can be as small as 2MB, if Windows doesn't like that it may resize it to a bit bigger size.

Hi John:
Thank you for your help.
I have only one hard drive but I have 2 GB memory. How large is the "small " page file that should be kept on the each system partition?

Just to make sure I understand what to do:
The OS on C will have a small page file on C and a "large" page file on E.
The OS on D will have a small page file on D and a "large" page file on E.
The small page files should have the same size parameters.
There is actually only 1 "large" page file on E which both operating system use.
Both operating system Virtual Memory pages should specify the same size parameters for the page file on E.
??Correct

See in-line below.

This is a dual boot system with Windows XP Pro installed on both bootable partitions. There is one hard drive with five partitions. Both operating systems use the same letter designations. The two operating systems use volumes C and D. Volumes E, F and G contain data. Volume E is seldom accessed.

Currently volumes C and D have their own page files (on the same volume as each opeating systems). In order to save some space on C and D, I I would like to remove the page files from C and D and create a page file on E.

If I do this, may I use the same page file for both operating systems?
Yes.


I find this to a bit confusing and I would very much appreciate detailed instructions for doing this.
Just set the pagefile for each operating system in the usual manner: System Properties>Advanced>Performance>Advanced>Virtual Memory. It's usually best to keep a small pagefile on the system partition, this pagefile is needed to capture memory dumps on system failure. Having the pagefile on a partition other than the system partition on the same disk is usually not a recommended practice, it would be best to move it to a different hard disk. You may see a performance hit when you do this, how much of a hit you see will depend on how much memory you have in the computer and how you use your computer. If you have lots of RAM or if you only do light work with the computer the hit may not be noticeable or hardly noticeable at all.
