Can you describe in more detail what the behavior you see is? How long does the broker take to dispatch the first, second, third, etc. matching message? Note that I'm not asking how long it takes for the message to be consumed; if your consumer code is slow, there's nothing ActiveMQ can do about it.
You can see the number of messages dispatched to each consumer via JMX or the web console, and you can see it change by refreshing repeatedly. Also, what proportion of the messages match your selector? And are there any other consumers on that queue at the time?

Dequeue by selector (JMSCorrelationID='...'), and the performance is REALLY bad. It seems like MessageConsumer is waiting MessageDispatchChannel to get all the messages from server. So in this case, How can I solve the problem?
