You should be able to get approximately similar performance at the 
consumer end as you get on the producer end.

So with that in mind:

* Are you setting prefetch count (basic.qos)?
* Are you using a different client library?
* How many consumers are you attaching to a queue?
* What performance do you get consuming the messages with PerfTest?

$ runjava.sh com.rabbitmq.examples.PerfTest -h amqp://user:pass@server 
-x0 -p -u <queue-name>
