Round robin will also make it more likely that the messages are consumed in close to the original sequence. If you allocate a chunk of 150 messages to the first receiver and the next 150 to the second receiver (I think this is what you mean by chunking?) then message 151 will be received at the same time as message 1. If you were in line at the bank with 150 people in front of you, you'd think it was your lucky day! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3962796#...
