     [ https://issues.jboss.org/browse/WFLY-4681?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Marek Kopecký updated WFLY-4681:
--------------------------------
    Description: 
Based on [~ctomc]'s comment in https://issues.jboss.org/browse/JBEAP-149,
perf team should do some testing and suggest best values for java memory settings in WildFly (-Xms, -Xmx, ...). This settings need to be completely reevaluated as EAP7 moved to JDK8 as requirement.
JDK8 doesn't have PermGen space anymore but metaspace, this completely changes how memory settings need to be tuned.
