Thanks for the response Rob, I'll give it a try. 


Switch to AMQ 5.0 - release candidate is here:

http://people.apache.org/~chirino/apache-activemq-5.0.0-RC3/maven2/ 
org/apache/activemq/apache-activemq/5.0.0/
maven 2 repo: http://people.apache.org/~chirino/apache-activemq-5.0.0- 
RC3/maven2
maven 1 repo: http://people.apache.org/~chirino/apache-activemq-5.0.0- 
RC3/maven1

Message Producer flow control can be turned off in 5.0 - see:  http:// 
activemq.apache.org/producer-flow-control.html - which is what's  
causing the slow down.

You can set size limits on memory, temp storage and store too - e.g:

<systemUsage>
	            <systemUsage>
		            <memoryUsage>
	    	            	<memoryUsage limit="10 mb"  
percentUsageMinDelta="20"/>
		            </memoryUsage>
		            <tempUsage>
	    	            	<tempUsage limit="100 mb"/>
		            </tempUsage>
		            <storeUsage>
	    	            	<storeUsage limit="1 gb" name="foo"/>
		            </storeUsage>
	            </systemUsage>
	    </systemUsage>




cheers,

Rob
