[ https://issues.jboss.org/browse/WFLY-5822?page=com.atlassian.jira.plugin.... ] Richard Achmatowicz edited comment on WFLY-5822 at 1/22/16 8:57 AM: -------------------------------------------------------------------- In the clustering meeting yesterday, Rado mentioned that part of the difficulty here is that we are comparing EAP6 source code + JDK 6 to EAP 7 source code + JDK 8, and that there are big changes in heap management in JDK 6 vs JDK 8 (removal of permGen and introduction of metaSpace). So, we did a comparison of EAP 6 vs EAP 7 using the same JVM - JDK 8. Here are the results (on two server nodes instead of four): https://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/mvinkler_eap-7x-stre... http://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/mvinkler_eap-6x-stres... Using the same JVM, EAP 7 hits 13,000 reqs / sec versus EAP 6 hitting 10,000 reqs / sec. Running the same 2 server test for EAP 6 using JDK 6 only yields marginally better results: was (Author: rachmato): In the clustering meeting yesterday, Rado mentioned that part of the difficulty here is that we are comparing EAP6 source code + JDK 6 to EAP 7 source code + JDK 8, and that there are big changes in heap management in JDK 6 vs JDK 8 (removal of permGen and introduction of metaSpace).
