    The items you mention above are all recommendations for scaling ActiveMQ as listed in the How do I configure 10s of 1000s of Queues in a single broker? page. I’ve utilized each of these tactics in various situations at customer sites and found that they help considerably.

    • The NIO transport is good for using less sockets when there are a high number of connections into a broker vs. the TCP transport. This efficiency can improve the overall performance of the broker.

    • I almost always recommend setting org.apache.activemq.UseDedicatedTaskRunner=false simply because it helps considerably with performance.

    • Disabling tight encoding is a subtle change and difficult to see the benefit. It depends on the types of messages that you’re sending.

    • The KahaDB outperforms any of the other stores for persistent messaging with ActiveMQ, especially on the trunk. There is a bug that is fixed only on the trunk currently that causes a dramatic increase in persistent messaging performance that will be part of 5.3.1 and 5.4.

    I know that this info isn’t concrete, but I hope it still helps.
