[ https://issues.apache.org/jira/browse/JAMES-2332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16352014#comment-16352014 ]
Tellier Benoit commented on JAMES-2332:
---------------------------------------
See https://github.com/chibenwa/james-project/tree/JAMES-2332 for a quick fix using ThreadLocal.
Remains to fix *delays* as well as *flush*.

> Key: JAMES-2332
> URL: https://issues.apache.org/jira/browse/JAMES-2332
> Project: James Server
> Issue Type: Improvement
> Components: Queue
> Affects Versions: 3.0.0, master, 3.0.1
> Reporter: Tellier Benoit
> Priority: Major
> Labels: perfomance
>
> As stated here: https://activemq.apache.org/artemis/docs/1.0.0/perf-tuning.html (section anti-patterns)
> Re-use connections / sessions / consumers / producers. Probably the most common messaging anti-pattern we see is users who create a new connection/session/producer for every message they send or every message they consume. This is a poor use of resources. These objects take time to create and may involve several network round trips. Always re-use them.
> Note that a JMS section needs to be "thread local". Rationals: the rollback operations rolls back the entire session.
