Aaron Whiteside commented on CAMEL-7950:
----------------------------------------
Connection pooling is implemented by the SJMS component, and a single
connection should be able to handle upwards of 5-6K messages a second.
> SJMS's Producers creates a new session per message request, this is both a
> performance issue and problem when using transactions

> 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.
