> Using Solaris 10 DTrace, I found a couple intense synchronization pinch-points in the Broker. Without altering the locking semantics, I converted the synchronized methods and one synchronized code block to the JDK 1.5 ReentrantLock. There was a pretty significant performance benefit with this change. I've attached the code, together with the old synchronized code commented out for ease of change examination.
