JMS

  • Close resources (e.g., connections, session objects, producers, and consumers) when you’re finished with them.

  • Start the consumer before the producer so that the initial messages do not need to queue as they wait for the consumer.

  • Use separate transactional sessions and nontransactional sessions.

  • Use nonpersistent messages, as they are faster than persistent messages.

  • Use shorter messages, as longer messages take longer to deliver and process.

  • Specify the lowest redelivery count and time-to-live that the application can accept.

  • Maximize message throughput by tuning the delivery capacity.

  • Use asynchronous reception of messages with the MessageListener interface.

  • Process messages simultaneously with ConnectionConsumers and ServerSessionPools .

  • Throttle very high-volume message delivery to a rate the consumers can handle. Use load-balanced message queues if necessary.

  • Duplicate-delivery mode is the fastest possible delivery mode, followed by auto-acknowledgment mode. Try to avoid client acknowledgment mode.

  • Use publish-and-subscribe for large numbers of active listeners, and point-to-point connections for few active listeners.
