<div dir="ltr">Thanks Michael for that super fast reply,<div><br></div><div>That was what I was actually questioning... across all threads, 91% of the time is spent in the connection thread and all of it is in reading the socket which I found somewhat suspicious, knowing how much processing needs to happen per message. �The other 9% is spent in "my code". �Is it really true that it is so time consuming for the connection thread to need 9/10ths of the time? �Also - I'm only seeing 400msg/s (even when I comment out all my code) from a durable persistent queue with ACK, lending more weight to my suspicions that something is not quite right here (I have basic QoS at 100msg and a single thread+channel here). �</div>

</div>Java client uses a separate thread for network activity (called "main loop"), one per connection.<br>
<br>
So in that thread, 100% of time is spent reading from the socket. When a delivery arrives,<br>
it is dispatched to a work pool (every channel has its own, AFAIR).<br>
<br>
If you profile all methods, it's certainly very likely that com.rabbitmq.client.impl.AMQConnection$MainLoop.run will be at the top of<br>
the overall table.<br>
<br>
You can try excluding certain classes/methods/threads from the profiler. That will<br>
give you a more informative insight.<br>
