    JBoss AS 6.0.0.M5 performance & memory consumption

    Christoph Rettig Newbie

      Hi, I recently upgraded a JBoss 4.2.3 GA installation to JBoss 6.0.0 m5 and now I am facing performance problems:


      When starting JBoss 6m5 the startup takes approximately 5 to 6 minutes (in comparison to 35 seconds with the old installation) and the memory

      consumption is huge (about 300-500 MB instead of 50-100MB).


      What I am also facing is that the JBoss 6m5 memory grows up without putting any load on the server (so its just started up, no users

      are working on it) from 300MB to about 500MB, then the garbage collector kicks in and removes about 200MB; this goes on repeatedly


      I have attached screenshots of JConsole of both the old and the new installation so you can have a look (note that both installations

      are standard, I did not do any performance tuning or change the configuration except placing my wars in the server).


      Do you have similar experience with this release or is there a release which should be preferrable used (I also tested the latest JBoss 5

      release and it showed similar behaviour)?


      Any help on this topic appreciated.
