So which one is better for high volume traffic ? I've heard numerous discussions on this subject and some people believe that a topic with a message selector is better. Here's what I think. There's a performance penalty for creating/destroying temporary queues and each one created consumed resources. With the topic approach, you just create it one (statically) and you're done. There might be some performance hit because of the message selector but as Tim said, it's negligible. So it appears on paper, that Topics with message selector is better.
