That is correct, as long as you don't have to worry about that the synchronizing internally in QF/J does not guarantee the message order under contention, but should yield a higher throughput. See the fairness discussion at https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/locks/ReentrantLock.html Best regards Øyvind Matheson Wergeland CTO Mobile: (+47) 95 16 16 88 E-mail: oyv...@om...
