Hi, More details about the scenario. We are creating message only once and sent it 500000 times. We have an emitter which route is configured from a vm channel to JMS topic. Consumer is receiving messages from this JMS topic. In the original test, emitting is configured with concurrentConsumers=30. To isolate from where the problem may come from we have switched this property to 1, but the degradation is the same - 20%. So seems that the reason is not related with changes in this direction.
