Edit Question
Title
Body
I read slides from this year's UberConf and one of the speakers is making the argument that Spring JMS adds a performance overhead to your message queue system, however I don't see any evidence to support that in the slides. The speaker also makes the case that point-to-point is faster than the traditional "publish-subscribe" method because each message is sent only once instead of being broadcasted to every consumer. I'm wondering if any experienced Java messaging gurus can weigh-in here and clarify a few technicalities: Is there actually a performance overhead incurred by using Spring JMS instead of just pure JMS? If so, how and where is it introduced? Is there any way around it? What actual evidence is there to support that P2P is faster than the pub-sub model, and if so, are there ever any cases when you would want to pub-sub over P2P (i.e. why go slower?!? )?
