Hello there! My application uses JMS heavily. It is a series of 
MessageListeners that through a central router communicate with each other. 
Almost all of my listeners are created as jms clientes with MessageConsumers 
(the reason for that is because I was not able to create mdbs "on-the-fly" on 
my custom deployer).

After running some stress tests, I've noticed that for those listeners, they 
consume the message really fast, for instance, one endpoint redirecting to 
another never takes more than 200ms. 

The last endpoint on the chain tough, sends to a queue consumed by and MDB. 
This one though, decreases the response time with the message load. For 
instance, with 1 message, it takes 700ms to consume, but with 300 it takes over 
40s to consume the last message.

I always thought that MDB was a pool with concurrent consumers to the same 
destination. I've increased the pool size on standardjboss.xml but no success 
at all. Is there an way to increase the performance?

Regards
