1. Re: JBoss AS 6.0.0.M5 performance & memory consumption
dkozlowski Dec 9, 2010 4:07 PM (in response to christoph.rettig)So This isn't going to help you with your problem , but it looks like you have remote jconsole working with JBossAS 6M5 I have been attempting to accomplish this , but haven't been able to. Would you be able to share the settings you used to get Remote JMX enabled ?

Hi, I recently upgraded a JBoss 4.2.3 GA installation to JBoss 6.0.0 m5 and now I am facing performance problems:
When starting JBoss 6m5 the startup takes approximately 5 to 6 minutes (in comparison to 35 seconds with the old installation)
Is that with your application deployed or without it?

mreasy Dec 10, 2010 5:54 AM (in response to christoph.rettig)Hi Christoph,
see http://community.jboss.org/thread/159659 for a similar comparison between JBoss4.x and 6.
In my tests (lasting for about 1-2 days at most) I also monitored memory consumption, but that was never showing a problem.

christoph.rettig Dec 14, 2010 3:04 AM (in response to dkozlowski)Hi Daniel, I am using the following environment
JAVA_OPTS_STD="-Xmx1024m -XX:MaxPermSize=256m -Dguid=jboss -Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false -Djava.rmi.server.hostname=${INTERFACE}"JAVA_OPTS_JMX="-Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.port=8089 -Dcom.sun.management.jmxremote.ssl=false"JAVA_OPTS_LOGGING="-Dlog4j.configuration=file://${JBOSS_HOME}/bin/log4j.properties"JAVA_OPTS="${JAVA_OPTS_STD} ${JAVA_OPTS_JMX} ${JAVA_OPTS_LOGGING}"export JAVA_OPTS
and this works out :)fine

5. Re: JBoss AS 6.0.0.M5 performance & memory consumption
christoph.rettig Dec 14, 2010 3:06 AM (in response to jaikiran)Hi, its with my applications deployed but my application are all jsp clients that do not do anything actively, so its just a JBoss having a few jsp pages loaded and I guess this should not result in that much resource consumption. Also I would expect that the startup should be not 5 minutes when having
deployed all the applications once?

christoph.rettig Dec 14, 2010 3:08 AM (in response to mreasy)Hi Rico, so you did not have this long startup time with your tests?

No. But maybe it's worth to tell sth. about your hardware. There may be other key components - like JBoss6 does more I/O related and less DB related operations than JBoss4 regarding the messaging.

8. Re: JBoss AS 6.0.0.M5 performance & memory consumption
christoph.rettig Dec 14, 2010 4:14 AM (in response to mreasy)I did my tests on a linux (RedHat) machine that is the same running the JBoss 4.2.3 GA
Linux dmsdev 2.6.26.5-vmware-atop-35 #2 SMP Tue Sep 23 16:01:36 CEST 2008 i686 athlon i386 GNU/Linux
which has one CPU and 3 GB of RAM.
As I compared the performance on the same machine running the old system I would not think that the hardware is the bottleneck.
Also I observed that the startup time of the JBoss without any applications deployed takes ap. one minute in comparison to the old
JBoss 4.2.3 GA which took about 20 seconds.
I guess I will wait until there is a GA release of JBoss 6 and then do my tests again - for me it seems that the current system is too unstable
to be used:(

For me on my Ubuntu system, a clean 6.0.0.CR1 boots approximately in around 20-23 seconds.

I don't think that's going to help, since there's no known performance issue that's been marked for 6.0 Final release. So let's narrow down the issue first. Install a clean 6.0.0.CR1 and start the default profile (without any of your applications) and post the entire logs that you see on the console. That would be a first step to see what's wrong.
