We're publising messages with a rate between 1000 msg/sec and 2000<br>
msg/sec in our dev machine. This is OK for us in our current dev status.<br>
<br>
The problem is with the delivery/ack speed. We're getting at most 150<br>
msg/sec with all our logic disabled : this means we are just<br>
deserializing and ack the message.<br>
This is creating a bottleneck.<br>
<br>
I was excepting similar numers to publshing, now I wonder if my<br>
assumption is correct.<br>

You should be able to get approximately similar performance at the consumer end as you get on the producer end.<br>
<br>
So with that in mind:<br>
<br>
* Are you setting prefetch count (basic.qos)?<br>
* Are you using a different client library?<br>
* How many consumers are you attaching to a queue?<br>
* What performance do you get consuming the messages with PerfTest?<br>
<br>
$ runjava.sh com.rabbitmq.examples.PerfTest -h amqp://user:pass@server -x0 -p -u <queue-name><br>
