Thanks Tim. I tried without message persistence and although I did get higher throughput it still didn't scale too well.
1 producer -13K msg/s 5 producers - 16K msg/s 10 producers - 17K msg/s When compared with RabbitMQ and Kafka, it doesn't appear to scale too well when increasing the number of producers. It may be something in my environment but I'm pretty much using a vanilla ActiveMQ installation.
