Have you configured a connection pool? You need to use that for higher performance.

> SJMS's Producers creates a new Session per message request, this is both a performance issue and a problem when using transactions.
> Sessions should be cached in ThreadLocal for performance reasons. Of course you may want to limit the total number of cached sessions or even implement a stack/queue of sessions to reuse. As long as a new session isn't created for every single message produced to a Queue/Topic.
> Second the same session should be used for any consumption and production to any queues by a thread when transactions are enabled. If a single route is consuming from JMS and producing to JMS, one would expect the same session to be used to provide atomic consumption and production to the queues/topics involved.
