W3WP.exe

Hi,

In my production server which hosts an ASP application(Employee self
service), serving for atlest 6000 users. Everything goes fine until the user
is minimal, but during peak period(expect the user hits to be more than
1000), the w3p.exe(Image name), Network Service(Username) shoots the CPU
usage to 100%.
Adding to the woes, it affects the DB server too...

I have limited the "Web site connections" to 100 (IIS 6.0 ---> Performance
tab), and even in Application pool. Let me do i need to spell out some more
details.

Re: W3WP.exe

Most likely this is not a 'bug' but an artifact of the code that is running.
When you have 1000's of people asking a server to do work, then the code
needs to be exceptionally performant.

You could use IISState to take a snapshot during a high CPU time and see if
there is a particular page/include file that is causing excessive CPU usage.
That would allow you to look at the code and see if it can be further
optimized to improve scalability.
