You could use the Debug Diagnostics Tool to troubleshoot high CPU usage by a process in IIS,
Please follow the steps below, I think it’s available for you to troubleshoot this issue.
Configure Performance Monitor logging
Disable Debug Exception Catching
Create a dump file
Disable Performance Monitor logging
Analyze the dump file
For reference- http://support.microsoft.com/kb/919791
In addition, you can also try Fiddler, it captures HTTP(S) traffic and logs it for the user to review. It can also be used to "fiddle" with HTTP traffic as it is being sent. By default, traffic from Microsoft's WinINET HTTP(S) stack is automatically
directed to the proxy at runtime, but any browser or application (and most mobile devices) can be configured to route its traffic through Fiddler.
Please let me know if there is anything that I can do to help.
