IIS+ASPNET2 Very Slow with huge Page Faults

Hi all,

We have four Windows 2k3 servers running IIS and hosting a ASP.NET 2.0
website/application. Throughout the day performance slowly degrades until
the scheduled recycle occurs at 1:30am. The server usage only reports a few
hundred megs of RAM for w3wp.exe (200-300) with over 2.5 gigs free of
physical memory and the CPU usage hovers somewhere around 5-10% utilization.
At any given time there are around 50-60 users on each server. When
investigating the problem, I noticed that the w3wp.exe process has somewhere
around 260 million page faults after running for only 2 days. Does anyone
have an idea as to why performance is becoming so bad, or why there were so
many page faults in such a short period of time?

Thanks in advance!
