The following two Performance Monitor counters have been added to diagnose and monitor ASP.NET applications:
Requests Current: The number of requests in the application request queue.
Requests in Application Queue: The current number of requests, including those that are queued, currently executing, or waiting to be written to the client. Under the ASP.NET process model, when this counter exceeds the requestQueueLimit that is defined in the <processModel> configuration section, ASP.NET begins rejecting requests.
