How a message is sent to the subscriber depends on the type of connection. In JBoss you have 4 different ways to send message:
- in JVM
- OIL (one socket connection for each JMS connection)
- UIL (one, multiplexed socket connection)
Thus the anwser is: IT DEPENDS but whenever it goes over the wire each message is sent on its own (broadcast would bring in limitation based on the network topology which is not desired). For durable subscription message can be sent out of sequence and therefore such a burst would not work.

Thnx for your reply, it's a lot clearer now. We've decided to make some changes so broadcasting is no longer
