Hi,

I'm going to be placing a large number of messages in a queue (100,000+) and 
then processing them one by one, and would like to allow the user to see their 
number of outstanding messages in the queue. There may be other people's 
messages in the queue as well, so total size of the queue doesn't help here.

I know from:
http://wiki.jboss.org/wiki/Wiki.jsp?page=IGetSlowPerformanceWithMessageSelectors
that JBossMQ will go slowly when using message selectors with a large number of 
messages in the queue because it uses the 'read and skip' approach, essentially 
going through each one, one by one.

Is JBoss Messaging going to exhibt the same behavior or will I be able to get a 
fast count of the number of messages in the queue using a message selector (or 
something similiar)?

Thanks,

Mark
