    How to improve the time of response of the Gatein?

    Elias Barrientos Garcia Newbie

      Hello friends of the forum, already I am finishing my portal in gatein for a company but I notice that the time of response is very slow.
       
      What must I do to improve it?

      Someone that I have applied

      Lots  of Requests ?  check JBoss thread pool

       

      JBoss thread pool is defined into conf/jboss-service.xml

      1. <mbean code="org.jboss.util.threadpool.BasicThreadPool" 
      2.    name="jboss.system:service=ThreadPool"> 
      3.    <attribute name="Name">JBoss System Threads</attribute> 
      4.    <attribute name="ThreadGroupName">System Threads</attribute> 
      5.    <attribute name="KeepAliveTime">60000</attribute> 
      6.    <attribute name="MaximumPoolSize">10</attribute> 
      7.    <attribute name="MaximumQueueSize">1000</attribute> 
      8.    <attribute name="BlockingMode">run</attribute> 
      9. </mbean> 

      For most applications this defaults will just work well, however if you   are running an application with issues lots of requests to jboss (such   as EJB invocations) then monitor your thread pool. Open the Web  Console  and look for the MBean jboss.system:service=ThreadPool.

       

      jboss tuning

      Start a monitor on the QueueSize  parameter. Have you got a QueueSize which reaches MaximumPoolSize ? then probably  you need to set a higher MaximumPoolSize pool size  attribute

       

       

      Set -Xms  and -Xmx to the same value

       

      By default, the virtual machine grows or  shrinks the heap at each collection to try to keep the proportion of  free space to live objects at each collection within a specific range.

      Setting -Xms and -Xmx to the same value. This  increase predictability by removing the most important sizing decision  from the virtual machine.
