  • Is there any performance tuning documentation for JBoss?
  • Please suggest and provide any documentation and sets for application fine tuning and GC handling best practice in production environment?
  • Need some guidance on improving the JBoss EAP performance.
  • Want to know, is there any JVM Memory Recommendation by Red Hat?
  • While running the Jboss EAP 5.2.0 application servers on RedHat Linux servers with 32G physical memory. The existing parameters for Java Virtual Machine are as follows:-
        JAVA_OPTS="-Xms1303m -Xmx1303m -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Dsun.lang.ClassLoader.allowArraySyntax=true" 
  • Is there any best practice to set these parameters for production machines such that we can utilize the memory available and maximize the performance?
  • What are the considerations if we would like to change these parameters?
  • Best practices for peformance tuning and troubleshooting
