Johan Stenberg commented on QPIDJMS-402:
----------------------------------------
Creating a new producer in each iteration was not on purpose but a mistake. I
changed the code and removed the semaphores. Running the test case I now get
these results:
v0.33.0:
Sent: 33844 msg/s Received: 35829 msg/s
Sent: 34337 msg/s Received: 35908 msg/s
Sent: 33868 msg/s Received: 32684 msg/s
Sent: 33907 msg/s Received: 35201 msg/s
v0.34.0:
Sent: 1097 msg/s Received: 973 msg/s
Sent: 1905 msg/s Received: 1582 msg/s
Sent: 3066 msg/s Received: 1638 msg/s
Sent: 2663 msg/s Received: 1666 msg/s
Still the new version is 10-30 times slower.
I now used openjdk 1.8.0u171 64bit on Windows 7 64bit (8core,16GB RAM).
I attached a maven project to reproduce the issue. You can now switch qpid jms
version via the qpid-jms.version system property:
{noformat}
mvn test -Dqpid-jms.version=0.33.0
mvn test -Dqpid-jms.version=0.34.0
{noformat}
> Massive performance degradation in 0.34.0
