Re: [jboss-user] [Performance Tuning] - Memory consumption 1h after JBoss start

by Peter Johnson

Peter Johnson [http://community.jboss.org/people/peterj] replied to the discussion "Memory consumption 1h after JBoss start" To view the discussion, visit: http://community.jboss.org/message/553989#553989 -------------------------------------------------------------- Ruchir, your suggested newsize is too small for the heap size specified - the newsize should be 1/3 - 1/4 the size of the heap. By the way, based on my tests, if you do not specify a newsize, JDK 6 eventually adjusts it to about 1/3 - 1/4 the heap size (just realized that was with the standard collection, not the CMS collector, but I suspect that letting the ). Setting MaxTenuringThreshold to 0 is a bad idea - I puts a larger strain on the CMS collector and degrades overall applicaiton performance. It is much better ot let needed objects survive a few minor collections before being tenured, and thus let the minor collector gather all the garbage, than requiring the CMS collector to collect objects that die soon. Besides, setting the UseConcMarkSweepGC sets MaxTenuringThreshold to 0 by default (and also sets the survivor spaces to a really small value. It is not always advisable to set UseConcMarkSweepGC. You must test your application both with and without it to determine hte best performance. Also, with UseConcMarkSweepGC, during a major collection, one of your CPUs will be dedicated to garbage collection. If you have only 2 CPUs, then you will reduce the amount of load your app can handle by 50%. For suggestions on how to gather GC data and analyze it, see these white papers: Java Garbage Collection Statistical Analysis 101 Java Garbage Collection Performance Analysis 201 (this white paper discusses the CMS collector and its gotchas) at http://www.cmg.org/cgi-bin/search.cgi?q=java+peter+johnson&x=30&y=10 http://www.cmg.org/cgi-bin/search.cgi?q=java+peter+johnson&x=30&y=10 h2. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/553989#553989] Start a new discussion in Performance Tuning at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [jBPM] - Can a mail node stop to contact mail server and just generate a mail file?

To view the discussion, visit: http://community.jboss.org/message/553987#553987 -------------------------------------------------------------- Hi HuiSheng: Thanks a lot for your help. We realize MailProducer can solve our concern (2) and (3), but the problem is our concern (1): the mail server is not reachable (known by either a check or a predefined flag) from the deploying host, and do not send mail (so there is NO exception thrown). Actually we are looking for a property in "jbpm.mail.properties" or a flag in somewhere (e.g. jbpm.default.cfg.xml) that can tell the MailSession to stop sending email. Or is there a way to turn off jbpm MailSession AND the "mail node" will not throw exception ? Your help is very appreciated.

I did upgrade to jboss-aop-2.0.0, but still not getting it. Sorry for using the term 'reflected'. What i meant to say was that i am not able to see the changes i made in the code after redeployment. The archive structure that is redeployed(JAR) is like this: / SessionBean HomeInterface RemoteInterface META-INF/ MANIFEST.MF ejb-jar.xml jboss.xml I am compiling and creating the jars externally. Later redeploying it into the deploy folder at runtime.

E.g. you can run the bundle tests with 750 bundles for all three framework with the following command lines: jbosgi/testsuite/performance> mvn install -Dtest=Bundle750TestCase -Dframework=jbossmc jbosgi/testsuite/performance> mvn install -Dtest=Bundle750TestCase -Dframework=jbmsc jbosgi/testsuite/performance> mvn install -Dtest=Bundle750TestCase -Dframework=felix A number of populations for both bundle tests and service tests are run mightly in this hudson job: http://jbmuc.dyndns.org:8280/hudson/job/jbosgi-performance-matrix http://jbmuc.dyndns.org:8280/hudson/job/jbosgi-performance-matrix For the latest results, see here: http://jbmuc.dyndns.org:8280/hudson/job/jbosgi-performance-matrix/ws/test... http://jbmuc.dyndns.org:8280/hudson/job/jbosgi-performance-matrix/ws/test... -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/553974#553974] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
