That's been my experience, also. When examining that counter under load, it's always at the maximum value - whatever value you put into the "limit simultaneous requests" setting in the CF Administrator. If you think about it, it makes sense - if you have queued requests, the threads allocated to handling requests should always be busy, given the relatively large intervals at which they're checked via performance counters. > Does anyone know of any way to see which requests these > are, or what is running and not dying? I'm not aware of any way to correlate this info, unfortunately. Conceivably, you could get the info by doing real-time logging of both incoming requests at the web server level (using an ISAPI filter, for example) and charting those against the other data you're collecting, but this would definitely be a non-trivial process, I think. Alternatively, you could do all this stuff in a controlled environment using a load-testing tool, which would give you a better idea of where the problems are.
