Background Thread CPU

Hi community,

What is the indication of high background thread CPU (more than 10%) on IIS App Pool .NET v4.5 2 process? What can we suspect from there?

Thanks.

Hi @leonatay 

The background thread CPU refers to everything that happens outside the monitored request. We can try to create custom services to capture the information that is done there.

Hello @leonatay,

Perfmon and DebugDiag, you can collect data that can be helpful in determining the cause of high CPU in application pools.

Once you have confirmed that a w3wp.exe process is experiencing high CPU, you will need to collect the following information in order to determine what is causing the problem:

  • A Performance Monitor data collector set.
  • A user-mode memory dump of the w3wp.exe process.

Have a nice day!
