Java Virtual Machines on Linux

[Ryan Lissack <ry...@abstraction.co.za>]

Hi,

I am interested to hear if others have used anything other than the Sun VM
for a production Tomcat system, running on Linux, and what their experiences
were.

from my previous experience, if your application uses heavy serialization
(HTTP session replication for example) you could gain better response time
with the JRockit from BEA....
never used the blackdown in production environement (just for development)
IBM 1.4 had several bugs (with properties loading...), I think they 're
fixed now

Ryan,

I've had good luck with the IBM JVM on Linux.  The Sun JVM is slower, uses
more memory, and isn't as stable.  At least that's been my experience with
it.  I'd narrow your options down to IBM and BEA.

Mike
