------------------------------------------

             Summary: Why ActiveMQMessageConsumer.dispatch copies message per \
listener  Key: AMQ-3949
                 URL: https://issues.apache.org/jira/browse/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.

line:1294
ActiveMQMessage message = createActiveMQMessage(md);
