Background; I'm currently running a system which at peak runs with about 15 million messages per hour using ActiveMQ, with several producers and consumers on the same topic.

Another vote for RabbitMQ. We're currently using a small RabbitMQ cluster that is averaging 5000+ msgs/sec and its not straining the sytem. At times, we've experienced bursts approaching 10,000 msgs/sec without any issues.

We have around 30 producers and 45 consumers spread out over a wide range of queues & exchanges.

Whilst ZMQ is generally faster, it does require more effort to be useful. Whereas RabbitMQ, I believe, provides the best of both worlds. Blazing fast messaging combined with ease of use and setup.
