    The best JVM

    tscondor Newbie

      HI!
      I have installed and optimized my jboss-3.2.6, but I have a question.
      What is the JVM for the best performance? JRockIt, IBM, Sun?

      Actually, I use Sun JVM 1.4.1 in my RedHat AS2.1.

      Excuse my bag english...

          This is not an official answer, ok... just my opinion! ;-)

          I have seen people saying that JVM 1.5 is light years ahead of JVM 1.4.1 because the GC options you could use.

          Ah... You're english is fine and you are in the wrong place to say sorry. Here in this forum everybody has a bad (or bag) English :-D lol

              Our benchmarks allways were about 30% better when using one of the JRockit VMs instead of the corresponding Sun VM (with just a few performance tweaks) ... unfortunately there seem to be some problems with the 1.5VM and JBoss.

              Okok ... now don't flame me for this comment. It was just a thing we mesured.

                I am using sun jdk 1.4.2 along with JBoss 3.2.3. can you suggest the best vm that could be used with this version of jboss so that performance can be improved.

                  Tried jdk1.5 vm with JBoss 3.2.3 At startup its giving the following exception.

                  What could be the reason for this ?

                    You need to upgrade to a later version of JBoss.

                      Based on our experience, JRockit is faster than the Sun JVMs but it contains also way more bugs. We chose a Sun JVM (the 1.4.2 one) because stability is more important for our business.
