[rabbitmq-discuss] Performance Hit when using Federation

Hello all,

I am investigating RabbitMQ for a project where we would need to 
federate multiple brokers. From my testing, I'm seeing acceptable 
throughput results as long as the server and client are bot talking to 
the same RabbitMQ server instance. However, as soon as I have the Server 
and Client talking to different servers using a federated exchange, I'm 
only seeing 1/4 of the throughput. Is this expected? I've looked at 
changing the prefetch counts, to no obvious avail. Any other items that 
I can tune?
