The answer really depends on a number of your application characteristics. See here for an example: http://jmob.ow2.org/jvm.html

To get an idea of some common criteria, try Googling: jvm performance benchmark

The answer is very hard, considering each JVM has different strengths and weaknesses.

I would look to the SPEC benchmarks - SPECjbb2005 & SPECjEnterprise2010 - they are current, peer reviewed and actively run by many companies (unlike the jmob.ow2.org benches, which were vaguely current in the Pentium 3 era!).

This one is pretty recent.

NOTE: Of course benchmarks are just that, a limited set of canned routines. They really do not give you a real view of the picture
