Best Linux JVM to use for Tomcat?
Hi All,
I have a site running with Tomcat 5.5.27 on Centos 5.2 32 bit. Which is the
best JVM on Linux to use with Tomcat?
I'm currently using Sun's JDK 1.6.0.
Thank you,
Fred

Guys,
Anything to say regarding JRockIt ? Is it still under development ?

hmm, what kind of heavy use?
We are using java version "1.6.0_05" for I think 6 Month now (since
end of march 08) and we had not a single issue with it and found it
better than 1.5.
Considering that the whole 1.6 release was maintenance and performance
release I would be surprised otherwise. It's actually first time I
hear omeone complaining about 1.6
Java(TM) SE Runtime Environment (build 1.6.0_05-b13)

P.S. We are running about 70 VMs on about 20 machines with top
services serving ~3000 requests per second and more with about 1000
threads.

Well, I don't know about always. I have yet to find a 1.6 JDK from
Sun that is even close to stable. With heavy use (especially heavy
multithreaded use), we have found that all of the available 1.6 JDK's
segfault.
The latest JDK (1.6 update 10) is less than a month old - and it is a
huge change set from the previous 1.6 release (1.6 update 7). I
wouldn't even think about it for production given Sun's history of
releasing crappy code.
1.6 update 10 should have been a major version change given the scope
of changes (see -
http://java.sun.com/javase/6/webnotes/ReleaseNotes.html )
We still use the latest 1.5 JVM / JDKs. Not that we want to. There
is just nothing else out there that doesn't crash under our workload.

I'm not sure about current versions, but several years ago, IBM had the
fastest JVM out there, although it used more memory than Sun's. I did,
though, hear that there was some weirdness in certain places like IO
(IBM's 32-bit JVMs were hosing java.io.File.length() reports by
accidentally using a 32-bit integer instead of a 64-bit one like they're
supposed to).
Whatever JVM you choose, make sure your test environment matches your
production environment!
