Hello there,
one of my servers is running windows 2003 and IIS 6.0. We have big
performance issues on that server and I found out that a high CPU usage
iniciated by w3wp.exe causes the problem. I couldn't find out what to do on
the server itself. I think it must be the application runnig on IIS. Could a
MVP please confirm that this is mostly something that i caused by an
application. So that I can give it back to our developers.
Thanks

w3wp.exe is the ASP.Net process, so if it is indeed using a lot of CPU, it
is the ASP.Net application that is causing it. However, this does not
necessarily indicate by itself that there is a problem with the ASP.Net
application. It is, of course, a service that may be serving many clients.
The only real measure is to check the CPU usage against the amount of
traffic being handled by the application.

Thank you for your quick answer.
Which performance Counters would you recommend to find out how much traffic
is handled by the application itself.
Thanks again,

Thank you very much for your help.
I found a shareware tool that creates statistics based on IIS logs.
This is enough to pass the problem to our developers as it shows that the
server has a high CPU Utilization without having a high amount of requests.

Sorry about the delay. IIS (Web Service) performance counters can tell you
how much traffic is coming to the site.

Hi All !
I am having the same issue as Tani had.
Is possible to use application pool and limit CPU and memory? I don't know
much of application pool but seems that it can recycle worker processes if
they are not in use.
Thanks!

I have an ASP.NET app that is running at around 60MB for the w3wp.exe. This
often jumps very quickly to 100/120 MB before shrinking again. It is also
using around 250MB of virtual memory.
Is it normal for the memory usage to jump around so much? Also the server
is a PIII 730 with 256MB RAM, running Windows 2003 Server.
I would appreciate information form other developers memory usage.

I am experiencing high CPU utilization with my ASP.NET application.
The w3wp.exe process uses 75%-80% CPU for about 10 seconds. I notice
this when the application first starts up, which I can partially
understand since ASP.NET compiles the application on the first access.
However, I also notice the high CPU usage by w3wp.exe after long
periods of inactivity. For example, if I stop using the site for 30
minutes, and then come back to the...
