If you use an embedded broker, you should consider using the VM (vm://brokerName) protocol instead of TCP (tcp://localhost:61616). But this has nothing to do with your issue... ;-)
If you have to achieve high throughput, you should consider using async messaging (two inOnly routes instead of one InOut). But that's what you do... What's about using the ConsumerTemplate to receive messages instead the PollConsumer? It sounds more correct for me, because you only want to return one messages as I understood your route...
