inetinfo.exe high cpu & page faults

inetinfo.exe high cpu & page faults

Windows NT4-sp6, IIS4
Dual 1.0g processors
512 mb Ram
Public Webserver for ASP application
ASP pages and PHP pages
both ASP and PHP pages pull recordsets from mysql service on another box.

We have a server that appears to be functioning properly, however after getting some calls recently about lagging pages, I noticed that the process inetinfo.exe appears to be running pretty high. I am really not sure if this is a problem, nor do I know when it started (if it is a problem).

I have downloaded and installed Sysinternals "Process Explorer" and "TCPView "
Process Explorer shows the cpu cycle's running as high as 99%, sometimes sustained around 70-80%, but it will drop down to as low as 10%.
The load on the two processors seems fairly balanced.
Process Explorer doesn't indicate any unknown process running..ie..malware, smtp..etc.
IIS is serving up ASP pages and does limit connections to SSL-128 only.
Throttling is not enabled.
There normally is less than 50 external clients connected at a given time, even when the CPU is high.
Our incoming internet connection is 512kb fractional T-1.

The one rather strange thing I have notice with Process Explorer is selecting the properties for inetinfo, the page faults is increasing and never decreasing. It is currently around 550,000,000
I have run perfmon, but don't see any issues with memory bottlenecks..although I could be wrong.

I have not rebooted the server yet.

I would greatly appreciate any suggestions for troubleshooting this.

I think the page fault count is cumulative so it will only ever increase.

Take a look at Solutions for Poor Server Performance which is mostly directed toward systems with similar roles to yours. Lots of good troubleshooting info in there.
