[jira] [Commented] (ARTEMIS-2070) broker can reduce buffer copies
with large messages
[ https://issues.apache.org/jira/browse/ARTEMIS-2070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16612385#comment-16612385 ]

GitHub user franz1981 opened a pull request:

ARTEMIS-2070 broker can reduce buffer copies with large messages
It includes several improvements on large messages:
- AMQP and OpenWire: it reduces the number of copies of the whole file size
- CORE: it allows to pool the chunks used to stream the message while consuming it
The policy chosen to pool the chunks makes use of the available credits, but can be made less aggressive if is safe enough.
