Kaffe is very slow for jit. In fact it is often outperformed even by
TYA, which uses extremly simple one-for-one translation of bytecodes.
I've used linux JDK1.2b2, with sun's jit - not hotspot,symatec or ms jit
(actually symantec and hotspot is almost 2 times slower ??)

And yes, what I was trying to show is that java has a lot more
possibilities to optimize, has better technology and support and is
faster than any of these 'very fast' freely available script languages.

Anyway, I still vote for guile for freeciv vm - speed isn't really
important here.
