Chris Custine commented on SM-1841:
-----------------------------------
I also think we should default to cachelevel=3. I have has similar issues
recently where users are using defaults and the performance was terrible and
certain things like ActiveMQ failover urls don't work as expected. If anyone
knows of a good reason not to change the default to cachelevel=3 let me know,
otherwise I will change this soon.
> New servicemix-jms endpoint out of the box uses listenerType="default"
> without any caching which drastically degrades performance.

> Project: ServiceMix
> Issue Type: Improvement
> Components: servicemix-jms
> Affects Versions: 3.3
> Environment: new servicemix-jms endpoint
> Reporter: Torsten Mielke
> Assignee: Chris Custine
>
> The [new servicemix-jms
> endpoint|http://servicemix.apache.org/servicemix-jms-new-endpoints.html] out
> of the box uses the default Spring JMS message listener and has no caching
> turned on. This really degrades out of the box performance. Compared to the
> [old servicemix-jms|http://servicemix.apache.org/servicemix-jms.html]
> endpoint the standard new endpoint is slower by a magnitude. Only with
> proper caching configured in the new JMS endpoint
> (cacheLevel="CACHE_CONSUMER") or by configuring for a different
> MessageListenerContainer (listenerType="server") will the performance be
> similar to the old JMS endpoint.
> Perhaps we can improve the out of the box performance and configure some
> default caching? At least we should document the need for a proper
> configuration of the "default" listenerType better.
