OK, I am in accordance with you in the majority of the things that you said. But this not dumb the question. The VM in MAC OS X have little performance of what in the Windows, Unix, Linux,…? I have the Kaffe JVM (http://www.kaffe.org/) installed in my iBook, I will be that it would be better of what the VM of MAC ? The VM of MAC the X are trustworthy?

"Mac" is not an acronym, you shouldn't capitalize each letter.

Apple's JVMs on Mac OS X are the only JVMs that I would trust to
function on Mac OS X and with any reasonable performance.

Apple's JVMs for Intel based systems should have about the same non-UI
related performance to the same version of JVM for Windows when
running on the same hardware. In fact I would bet that Apple's JVMs
for Intel based systems could even outperform the ones for Windows
because Apple has a more limited hardware set to target and hence
could better tune for the specific Intel processors Apple uses.

Apple's JVMs for PowerPC based systems likely will under perform the
Intel JVMs simply because the JIT compiler for Intel is much more
mature then the JIT compiler for PowerPC. Also traditional PowerPC
strengths (vector processing for example) don't benefit the JIT/JVM
greatly.

Finally talking about performance in the UI level of things is far
more complex of an issue... it can vary for countless good reasons.
