Miroslav Novak commented on WFLY-9835:
--------------------------------------

[~ashwini1r] Hi Nilesh, there is big difference between JBoss AS 6 and Wildfly 11. It's completely different code. Also AS 6 used JBoss Messaging broker which used database for storing messages.  Widfly 11 is using ActiveMQ Artemis which is using local file journal for storing messages. Thus Artemis is at least 10x times faster then JBoss Messaging.  

When you're running JMeter is number of messages per second the same?

> I have upgraded my application from Jboss6 with java 6 to WildFly11 with java 8 in dev environment.
> Note :
> I am facing some performance issues in WildFly11 as my 90% gets increased for same set of run as it was in Jboss.
> *And minor GC gets increased to 7 times as it was in jboss.*
> And there is no application level code changes in wildfly11.
> *Please find attached files for GC log and Heap dump related inputs.*
> Inputs :
> JVM parameters : Parallel GC with 4 threads , -Xmx6144m Xmx6144m  -XX:NewRatio=1 -XX:ParallelGCThreads=4 -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=1024m
> Parameters are same in Jboss 6 and WildFly11.
> Jmeter result overview for 100 users in 15 mnts with  250 sec rampup time.
> As all of our app server is on AWS with same configuration.
