What does it mean?
It means that IIS is free to use more than one thread to handle a single request, although not in parallel.
Basically, IIS tries to perform I/O operations asynchronously, thus freeing the calling thread for the duration of the operation. That thread is returned to the pool and can be used to handle other requests in the meantime.
When the asynchronous I/O operation completes, control can be returned to a thread other than the one that originally handled the request (since that thread can be busy elsewhere), so the request can continue being processed as soon as possible.
