While load testing an ASP.NET app, we find that the pages are taking 20-30 sec under heavy load.
We suspect this is because the pages are waiting for database calls or web services.
Is there a particular perfmon counter that can identify this sort of bottleneck on the web servers? CPU, Memory, and Disk are normal.
Or must we use a tool other than perfmon to track down this bottleneck?
