I suspect that's the main issue. With a prefetch count of 10 you don't 
need much network latency to ensure that the server sends 10 messages... 
and then has to wait before acknowledgements arrive.

In some future version of RabbitMQ it would be nice to indicate when a 
consumer is effectively being throttled by a low prefetch count. One day...

Cheers, Simon
