Load testing application for RabbitMQ with EasyNetQ
RabbitMQ.LoadTest comes in two parts, a publisher and a subscriber. In order to test the throughput of a given rabbitmq server start the subscribers and then start the publishers. It is recommended to run multiple copies of each attached to separate vhosts to increase the load. This is of course dependant on the environment you will be using RabbitMQ in. No need for many queues and connections if your usage will be light.
