    JBOSS on AIX very slow...

    Jay DeBruin Newbie

      Greetings. We purchased an application from a Vendor that runs through jboss as. The vendor said the program worked under AIX, but it's intolerably slow. We installed the same application on a windows 2003 server and it's more than twice as fast. We noticed strange thing on AIX. We purchased 2 GB of extra memory for the AIX machine just for the app server. The application takes 95 MB of memory to first load, then about 20MB for each user. When we start it in AIX, it loads everything into paging space, none of the application resides in memory. On windows everything loads into memory and stays there. It doesn't matter what Xms or Xmx settings we use the same thing happens. What kinds of settings should we check in AIX? Anyone have any ideas or hints?

      I haven't seen jboss before this, so if I'm missing any pertient info please let me know.
      The Vitals:
      AIX - JAVA 1.4.2.20 - build caix64142-20050929

      6 GB memory
      Java Opts - -Xss512k -Xms512m -Xmx2048m -Dprogram.name=Djava.awt.headless=true -Djava.net.preferIPv4Stack=true
