Performance comparison between ZeroMQ, RabbitMQ and Apache Qpid

Question

I need a high performance message bus for my application so I am evaluating performance of ZeroMQ, RabbitMQ and Apache Qpid. To measur

Answer 1

I've tested c++/qpid

I sent 50000 messages per second between two diferent machines for a long time with no queuing.

I didn't use a fanout, just a simple exchange (non persistent messages)

Are you using persistent messages? Are you parsing the messages?

I suppose not, since 0MQ doesn't have message structs.

If the broker is mainly idle, you probably haven't configured the prefetch on sender and receptor. This is very important to send many messages.
