There is no jit for it in the kaffe.org sources, that's the main reason
;) But you're most welcome to help out on one!
Yeah, the interpreter is rather slow. There are ways to speed up the

And of course, you could try either making the powerpc jit from janosvm
0.8.0  work with Kaffe, or merging in the JITs from Mono, or libjit
