[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=13140237#comment-13140237 ] 

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

Michal, that's great.

I just had a quick look at BaseDistributionInterceptor and there is trace level logging which gives more or less the same information that we need (maybe a little more than desired though). So, in the first instance, could you please re-run the job with TRACE logging on this class:

org.infinispan.interceptors.distribution.BaseDistributionInterceptor

This class handles remote gets and logs information about which gets were remote and which were not. It is likely that we can see the problem from this information without having to write a custom Byteman script.

> 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
> 7.0.0.ER2: [throughput|http://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/eap-7x-stress-ejbremote-dist-sync/4/artifact/report/graph-throughput.png]

> Just for comparison: ejbremote REPL_SYNC scenario *performs well* on the other hand:
> stress-ejbremote-repl-sync
> 7.0.0.ER2: [throughput|http://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/eap-7x-stress-ejbremote-repl-sync/3/artifact/report/graph-throughput.png]
