IIS webgarden tuning
Does anyone know which perfmon counters can assist in determining the number of web garden worker processes recommended?
I have searched the web and it seems like no one really knows when to use it, but simply try it and then check to see if it improved the performance.
It would be great to have a counter that could be used for this. For example, when the number of XXX threads go over 5 then an additional worker process is needed.

I went through a long discussion about this with some Microsoft tuning gurus a while back when one of our customers was having severe performance problems with a Sharepoint cluster. They felt pretty strongly that the defaults were good for most implementations. That answer didn't satisfy me at the time and probably doesn't help you, either.
As a tester with a system at hand which could benefit from such tuning (I assume), you're probably in a better position to answer the question for your organization than we are. Run a test with the default (or current) settings and then run another identical test with the setting increased (or decreased) and analyze the test results. I'm sure many of us would like to hear what you find!
Keep in mind than many of these tuning parameters are going to be sensitive to the specifics of a particular hardware and software configuration - so the best setting for somebody else's application may not be the best choice for _yours_.
