Hey,
we have been running some performance tests with our application (TomEE 7.0.5 based) and are stuck: Until 4 core VMs (or docker containers) we see a linear increase in performance, which is great and was anticipated. But after 4 cores, we barely get 10% (with 8 cores) more performance of the system. We used jmeter based load tests (SOAP calls) with 10/20/30/40 and 100 threads, VM to VM via 1gbit, and 4 GB of RAM. We played around with session bean pool sizes (min set to thread count, max to 1000) and stateful bean pool settings and also with jvm heap size and GC parameters, to no avail. Are there any more performance parameters we can toy around with in TomEE or Tomcat that you can recommend? Thank you and best Fabian
