If you are sending a lot of messages in a fairly constant stream it doesn't make a lot sense to me why you are setting maxBatchSize to a value other than -1, since the batch will be sent anyway when maxBatchSize is reached. Regarding the speed of bridging, this is a function of many factors including: The size of your messages Are the messages persistent? The bandwidth of your network The round trip time of your network The speed of the ActiveMQ server The Quality of service mode you are using. The speed of the JBM server So it's very hard to quantify. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241489#...
