HI James thanks a lot, now it's clearer, but I still cannot figure out why only a portion of the session available are used. Is it possible that I'm not feeding the consumer fast enough, even if the queue is not empty?
Yeah it could be. Try flood the queue with heaps of messages first before starting the MDBs?
Moreover, using maxMessagesPerSession=1000 means that the queue size is = #pending messages-1000 ?
It means that each session will get its own buffer of 1000 messages - just for that session - which will be buffered into RAM ASAP to boost performance. So you'll need more than maxMessagesPerSession * maxSessions messages on the queue at any point in time to avoid starving the other sessions. i.e. try a tiny value of maxMessagesPerSession (say 1) to get the concurrency right, then increase it as and when you've enough messages -- James ------- http://radio.weblogs.com/0112098/
