Performance Tuning - Thread Configuration

jie.deng Feb 3, 2003 8:46 PM

Hi There,

I've been looking for information on how to configure JBoss thread behavior, such as execution thread count, socket reader threads,... But I am not able to find any organized information on this (we did buy the official JBoss doc sets). What I am trying to do is to fine tune thread bahavior where I don't either over commit the running threads (therefore causeing too much context switching) or under commit the threads (create too long a processing queue). I feel now the default config has too many processing threads. I wonder if anyone has any pointer to this topic.

I've the same problem.

Try to increase the number of processor in tomcat or MaxThreads and MinThreads in Jetty app descriptor

Anyone has an answer to this ? I'm trying to find a configurable "thread count" or execute queues for thread execution. I know this is a very important performance tunable in WebSphere and WebLogic. Is there such a thing in JBoss ?

Another question is ... is there a JBoss performance tuning guide for the server ? I'm not looking for a best-practices EJB/CMP app development guide for performance... I'm looking more for server performance tuning like thread count, pooling, caching, transactions, memory management, app server I/O and other server tunables.

Thanks,
Trev

For Jetty, look in
<JBOSS_HOME>/server/<SERVER_NAME>/deploy/jbossweb-jetty.sar/META-INF/jboss-service.xml

Look at the section that resembles:

10
100
30000
5000
