I need a high performance message bus for my application so I am evaluating performance of ZeroMQ, RabbitMQ and Apache Qpid. To measure the performance, I am running a test program that publishes say 10,000 messages using one of the message queue implementations and running another process in the same machine to consume these 10,000 messages. Then I record time difference between the first message published and the last message received.

Following are the settings I used for the comparison.

  1. RabbitMQ: I used a "fanout" type exchange and a queue with default configuration. I used the RabbitMQ C client library.
  2. ZeroMQ: My publisher publises to tcp://localhost:port1 with ZMQ_PUSH socket, My broker listens on tcp://localhost:port1 and resends the message to tcp://localhost:port2 and my consumer listens on tcp://localhost:port2 using ZMQ_PULL socket. I am using a broker instead of peer to to peer communication in ZeroMQ to to make the performance comparison fair to other message queue implementation that uses brokers.
  3. Qpid C++ message broker: I used a "fanout" type exchange and a queue with default configuration. I used the Qpid C++ client library.

Following is the performance result:

  1. RabbitMQ: it takes about 1 second to receive 10,000 messages.
  2. ZeroMQ: It takes about 15 milli seconds to receive 10,000 messages.
  3. Qpid: It takes about 4 seconds to receive 10,000 messages.

Questions:

  1. Have anyone run similar performance comparison between the message queues? Then I like to compare my results with yours.
  2. Is there any way I could tune RabbitMQ or Qpid to make it performance better?
