[rabbitmq-discuss] HiPE slower

Wed Apr 9 10:02:02 BST 2014

Did some performance testing on a c3.4xlarge machine, with and without HiPE: 

Without HiPE: 
$ rabbitmq-java-client-bin-3.3.0/runjava.sh com.rabbitmq.examples.PerfTest
--uri $URI --time 20 --autoack -x 8 -y 16
sending rate avg: 17382 msg/s
recving rate avg: 240834 msg/s

With HiPE:
$ rabbitmq-java-client-bin-3.3.0/runjava.sh com.rabbitmq.examples.PerfTest
--uri $URI --time 20 --autoack -x 8 -y 16
sending rate avg: 5328 msg/s
recving rate avg: 55698 msg/s

Any idea why HiPE is slower on a 16 core machine? On smaller instances, like
m3.medium HiPE gives about 80% _better_ performance than without.
