Having multiple consumers with selectors on a queue is normally an anti-pattern (http://jira.jboss.com/jira/browse/JBAS-1348), and will always have poor performance compare to using selectors with topics. This will be true for any JMS implementation. However I am surprised there is such a difference in performance between JBoss Messaging and JBoss MQ since they do pretty much the same thing. What version of messaging are you using? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3973903#...
