FW: IIS processor power

We have 200+ domains on a Dell 2200 Server with 512MB RAM, 750MB Swap File,
NT Raid 1 Duplexing (9GB+9GB), Dual Pentium II 233Mhz. We are experiencing
a high number of Page Faults/sec. Hard drives are crunching away. We have
not been able to isolate the source of the Page Faults. Anyone have any
clues where I can look?

Page Faults range from 20-70/s to 300-2000/s. Sometimes Perfmon reports
sustained Page Faults ranging between 100-200/s. Here are some other
Perfmon counters. According to these I should not be getting such a high
level of Page Faults.

Object: Memory

% Committed Bytes in Use 17.133
Available Bytes 291442688.000
Page Faults/sec 106.838
Pages/sec 25.792

Object: Paging File

% Usage 2.148
% Usage Peak 2.263

Any help is appreciated.
