SmartThreadPool active threads and perfmon physical threads

Aug 27, 2013 at 7:32 AM
I have a .NET application which uses SmartThreadPool.

On monitoring this application using perfmon and adding the STP's Active Threads and the process' Number of physical threads counters, I got confused as to relation between them. What I deduced was the Active Threads will be a subset of the Number of physical threads. Is that right ?
Also, is there a relation between the process' Number of current recognized threads and STP's In use threads counters ?
