    800ms for: Get instance ....

    svenbeer Newbie

      Hi!

      I've got a question concerning a command that seems to take a lot of time. I enabled trace, because I was searching for a reasons of slow performance of my application (BMP EJB, some stateful session beans, JSP Frontend using Tomcat).
      Why does the command marked with !!! in the following log take over 800 ms to complete? And what options do I have to improve performance?

      I am using the standard BMP Instance per Transaction configuration with commit option B, because their is another application modifiying the database.

      I am pretty new to JBoss and hope that somebody can give me a hint what to try next.
