Richard Achmatowicz commented on WFLY-5822:
-------------------------------------------
With regard to remote accesses of keys:
7.0.0 jobs:
- jobs run with the Byteman rule RetrieveFromRemoteSource which checks for invocations of
the method BaseDistributionInterceptor.retrieveFromRemoteSource
- output found for this rule in the job output for random cluster nodes (in other words,
on one run, perf18 has to remotely retrieve a key, on another run, perf21 has to retrieve
a remote key)
- because this is a stress test and failures are not triggered, unless there is an ISPN
rebalance for reasons other than failure, the node with the remote key will have to make
that extra invocation on every access to that key
6.4.0 jobs:
- jobs run with the Byteman rule RetrieveFromRemoteSource which checks for invocations of
the method BaseDistributionInterceptor.retrieveFromRemoteSource
- no output found for this rule in the job output for any cluster node
MOre investigation to follow.
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
Priority: Critical
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:
[

6.4.0.GA:
