https://issues.jboss.org/browse/WFLY-5811?page=com.atlassian.jira.plugin....
]
Paul Ferraro closed WFLY-5811.
------------------------------
Resolution: Rejected
It is easy to misinterpret ASYNC performance results.
These graphs do not indicate a performance regression. On the contrary, the DIST_ASYNC
ejbremote stress tests show equivalent performance, while the DIST_ASYNC session stress
test indicate a welcome, but expected performance improvement.
Clustering performance regression in scenarios with ASYNC cache used
--------------------------------------------------------------------
Key: WFLY-5811
URL: https://issues.jboss.org/browse/WFLY-5811
Project: WildFly
Issue Type: Bug
Components: Clustering
Reporter: Michal Vinkler
Assignee: Paul Ferraro
Our clustering write-heavy stress tests show a performance drop of 7.0.0.ER2 bits
compared to 6.4.0 bits, when using ASYNC cache.
Compare these results:
stress-ejbremote-dist-async
7.0.0.ER2:
[throughput|http://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/eap-7x-str...]
6.4.0.GA:

Also, load scenarios, which use a stable load of 4000 sessions are affected.
