Hi! I have noticed huge performance difference in version 2.19.1 running on JVM 1.8 and JVM 11. I am currently running my tests on M1 Mac mini.
I was trying to implement ONLY_ONCE delivery client and noticed that messages are sent much faster (x 100 times) when I am running Artemis HA cluster on JVM 1.8 But that I think can be easily reproduced just by creating configuration: JVM 1.8: ./artemis create MR1 done! Your system can make 0,06 writes per millisecond, your journal-buffer-timeout will be 18136000 JVM 11: ./artemis create MR1 done! Your system can make 50 writes per millisecond, your journal-buffer-timeout will be 20000 That’s looks suspicious. Moreover I am constantly loosing messages when running on JVM 1.8 and never on JVM 11 (may be that’s just because of speed or poor client implementation) Regards Iliya Grushevskiy
