There was a great deal of change in the client to implement the extra 
bits needed to meet the JMS 2.0 specification requirements along with 
other changes to handle of the more interesting edge cases around JMS 
usages so it'd be hard to just pull out one change as the culprit 
without more research.  I'm not that surprised that there were some impacts.

What would be helpful would be to pull out one affected test case where 
you see this drop in performance into a standalone test so we could run 
it in the Qpid JMS test suite and do some digging.
