Subject [jira] [Created] (AMQ-3949) Why ActiveMQMessageConsumer.dispatch copies message per listener
Date Mon, 30 Jul 2012 03:21:33 GMT
Martin Chan Shu Ching created AMQ-3949:

             Summary: Why ActiveMQMessageConsumer.dispatch copies message per listener
                 Key: AMQ-3949
             Project: ActiveMQ
          Issue Type: Improvement
            Reporter: Martin Chan Shu Ching
            Priority: Minor

When the consumer receives a topic message, the message is copied in ActiveMQMessageConsumer.dispatch()
line 1294. If there are 10 consumers, the message will be copied 10 times. Wondering if that's
really necessary because we are doing performance tuning in our applications and found there
is high memory usage in the MQ layer.

ActiveMQMessage message = createActiveMQMessage(md);
