Well, since you asked:

0/ test, test, test: that is, test load and functionality under various
JVMs.  See which one performs best, per your requirements.

1/ Tune, tune, tune: there's much more to performance than just the
JDK.  You'll also have to take heap, GC, etc into consideration.

2/ install this same JVM + configuration in production.

Ideally, you'd have similar hardware in both your test and production
environments, such that any tuning you do could be applied to both.

Given what I see on the list, I get the impression most of the people
here (or at least, most of the posters ;) use Sun's JVM.  -but YYMV, and
thus, you'd do yourself a favor to test it for yourself.
