When I profile using xperf there are always cases when I see, that, say svhost(1552) "eating resources". I could then go to ProcessExplorer and see that svhost(1552) running like 10 services.

How to determine which of the services is a culprit? Is it possible to configure xperf somehow to see the statistics for each service?

Inspect the threads of the process, this will allow you to pinpoint the service itself.

But sometimes it is hard to say, which thread belongs to which service. Is it possible to definitely know, what service this thread belongs to? –  MajesticRa Sep 20 '11 at 19:46
    
@MajesticRa: The image name (a EXE, DLL or SYS file) should be enough to pinpoint the service, the stack of a thread lists which function of which images are being called... –  Tom Wijsman Sep 20 '11 at 20:36
    
Have to check it! Thank you! –  MajesticRa Sep 20 '11 at 21:31
