In this chapter, we provided a list of performance tuning tips that can be used to build a proper approach for the tuning of the performance of the RabbitMQ message broker. We discussed how to measure the performance using the PerfTest utility provided by the RabbitMQ Java client and monitor the performance in real time using either the management interface or third-party monitoring solution, such as Nagios, Monit, or Munin. At the end, we discussed how we can compare the performance of RabbitMQ against a few other message brokers that are widely used in practice and compete against RabbitMQ.
