-----------------------------
Resolution: Not A Problem
> 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 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);
