I have a new Windows 2008 Server up in tâ cloud and whilst checking it today, I noticed that memory usage was a bit higher than expected.
I have a lot of websites running on this box and each site has its own application pool. Looking in task manager, there are obviously quite a few w3wp.exe processes, but one in particular was using a lot of memory.
I was after a way of finding out which PID belonged to which application pool.
The answer was simple, I just ran this from the command line:
%windir%\system32\inetsrv\appcmd.exe list wp
This then returned all the PIDs and the attached Application Pool name for each one. Happy days.
