That's the most important counter for this context. It tells us the main queue never got anything really queued up (it never had more then 11,365 messages, which is "nothing" in a high performance environment). > > These don't look bad to me. > > note that you only have an action queue for one of your actions (action2), > all the rest of your actions are being handled by the main thread.

This is why I came to the conclusion that the only potential bottleneck I see is how fast imudp can pull out messages from the OS receive buffers. In my experience, failure here does not even manifest in increased CPU use by the imudp thread.
