Ron,
Check this article from MS:
http://support.microsoft.com/default.aspx?scid=kb%3Ben-us%3B314482
It contains some good information about the page file and how it works.
Towards the bottom of the article is the note:
NOTE: If your computer contains multiple hard disks, you can also create
a paging file for each hard disk. When information is distributed across
multiple paging files, the hard disk controller can simultaneously read
from and write to multiple hard disks. As a result, system performance
is enhanced.

Subject: [24hoursupport] XP Swap File Question
Hello Group,
Does anyone know how efficiently Windows XP manages
multiple swap files on different physical drives?
The question came up simultaneously at work and on a
developers list I belong to. XP allows you to have a swap
file on every drive, if you want. The questions that came
up specifically are (1) if the aggregate swap file space
on multiple drives is the same as the allocated space on
the C:\ drive, will there be any performance degradation,
and (2) is XP smart enough to select which swap file to
use to maximize efficiency, i.e. not one on the current
active drive, one that is large enough for the current
task without spanning swap files, etc.
A third question that came up is, is it possible to
manipulate/choose what swap file to use for a specific
task from a .net program (C++ or C#).
Basically, how do multiple swap files work under XP?
Thanks,
Ron
