RabbitMQ is ok in single server and has lots of flexibility but struggles at high throughput ( > 100k/sec) and the clustering setup is not great. There are also lots of edge case bugs.

If you don't need persistence, look at using nats.io which is a much more stable and reliable pub/sub system. You can build persistence on top of it or wait a few months until they finish their new project STAN.

Thanks! 100k is far more than I need, but I couldn't find something that would fit exactly my needs, so I ended up rolling my own.
