[jboss-jira] [JBoss JIRA] (WFLY-5822) Clustering performance regression in ejbremote-dist-sync scenario

[Richard Achmatowicz (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-5822?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13143735#comment-13143735 ] 

Richard Achmatowicz commented on WFLY-5822:
-------------------------------------------

[~lthon] thank you very much for the excellent Byteman examples!

The large logs problem can be worked around by shortening the duration of the test. However, the EAP 6.4 ISPN version (5.2.15) and the EAP 7 versions (8.0.1) are 3 major versions apart, so the logging is quite different in each and affords no comparison.

I'm on PTO for the next two days, but have set up two LT-Byteman jobs to start investigating via Byteman whichshould provide the information needed. 

Thanks guys for your great help!

> Compared to EAP 6, all SYNC scenarios have the same/better performance except of this one, wonder why?
> Compare these results:
> stress-ejbremote-dist-sync

> Just for comparison: ejbremote REPL_SYNC scenario *performs well* on the other hand:
