Richard Achmatowicz commented on WFLY-5822:
-------------------------------------------
It would be very helpful to see during a test to what extent remote gets are required when
accessing a session.
A small Byteman script to interrogate each Infinispan get to see whether or not the get
hit a primary, a secondary or a non-owner node.
This could possibly explain anomalies in performance due to the effects of distribution.
The script could keep a running tally of such statistics and spit them out ate the end of
the test.
Clustering performance regression in ejbremote-dist-sync scenario
------------------------------------------------------------------
Key: WFLY-5822
URL: https://issues.jboss.org/browse/WFLY-5822
Project: WildFly
Issue Type: Bug
Components: Clustering, EJB
Affects Versions: 10.0.0.CR5
Reporter: Michal Vinkler
Assignee: Richard Achmatowicz
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-str...]
6.4.0.GA:
[throughput|http://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/eap-6x-str...]
---------------------------------------
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-str...]
6.4.0.GA:
[throughput|http://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/eap-6x-str...]
