Martin Chan Shu Ching updated AMQ-3949:
---------------------------------------
Description:
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 to copy
the content 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);
