Is it possible to configure the above setup such that, the broker has to send the data message (generated by producer) only once, if both consumers are listening on the same multicast? The frequency of data is a lot higher than frequency of heartbeat or subscription/bookkeeping messages. And I would like to scale this against a higher number of consumers, eg 20. Thanks, Pawan. -- View this message in context: http://activemq.2283324.n4.nabble.com/Multicast-optimization-tp4668017.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
