Java Virtual Machines (JVM) and their performance comparison

Question

I was wondering if there somebody knows if there are some benchmarks which compare the following jvms.

sun jvm vs. openjdk jvm vs. rockit jvm vs. j9 jvm vs. apache harmony.

Which one is has the best performance?

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The benches listed at that link are many, many years out of date and no longer provide any sort of meaningful answer. I would not recommend them. – Trent Gray-Donald Jun 22 '10 at 01:58
Yes, I agree. I don't think most off-the-shelf benchmarks are useful unless you know why. My answer was just that I find old benchmarks helpful in understanding these why's. – Vineet Jun 22 '10 at 05:22

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

This one is ok - it's a pity that jrockit is not included in the benchmark. – markovuksanovic Jun 18 '10 at 20:00

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!).
