Performance of Java on FreeBSD vs. Linux and others

[Sharkie]

Forgive me for bringing up this issue again. I tried searching in the  
archive, and I could only find discussions from late 2006. Now that  
FreeBSD 7.0 is out and we have a new scheduler, can someone comment on  
performance of Java on FreeBSD vs. Linux and others? I tried following  
the old thread and I believe it was inconclusive rather than that  
FreeBSD is definitely slower. Yet, there was an argument on how much  
slower. I would really like to know this information because I will be  
doing heavy number crunching in Java. A 20% performance gain could  
save me 1-2 day at a time.

Thanks!
