When upgrading to AMQ 5.2, my application gets 10x slower. This is traced to the usage of reply queue. I have written a test case (will be attached.)
sender: 16.0 seconds spent for sending 8000 times, avg. 500.0msg/s
sender: 432.0 seconds spent for sending 10000 times, avg. 23.148148msg/s
I have tried arrange the steps a bit (see commented out line,) no help.
