Our Systems were all SuSE based Linux System on AMD machines. Well, both IBM and JRockit have excellent performance tuning manuals, but according to my experience, both JRockit 8x and IBM 1.4 are unstable on RedHat 7.3, as opposite to Windows and, I presume, to RedHat AS 2.1. That's why I stopped playing with them and switched to Sun. If next year we migrate to SuSE, I'll try again ;-) The drawback of Sun is that for unknown reasons there is no good documentation on GC and memory tuning. Only few articles and forum messages. But we got approx 30% increase after tuning. Cluster of 4 instances, 2 boxes (2 Xeon CPUs, 4GB, RedHat 7.3 each). Vlad --- This SF.net email is sponsored by: IBM Linux Tutorials.

RE: AW: [JBoss-user] JBoss On Linux
BTW, did you try the -Xincgc option for continuous GC on Sun's JVM? That would
probably give you the same results you were seeing in JRockit. Depending on how you
configure each you may not be looking at an apples to apples comparison.

Yes, in fact I expected to see a link to the storefront that would net him
some micropayments: a nickel per view:) My only concern is that they are now under
BEA's umbrella so the temptation to enhance or hobble when running or not running in
weblogic is there.

That's a pretty nice review. Does anyone else use JRocket on Linux?
What are there experiences?

hi peter,
i run jboss in the same exactly environment, but i don't seem
to be
running into these problems.
we found the ibm jvm to be the best for our scenario...maybe
you should
take a look at it.

Has anyone experienced similar problems?
