Hi,
I have tested running Kaffe 1.1.4 in MontaVista Linux on a PowerPC platform.
Thanks for testing Kaffe!

Looking at the README of the Kaffe 1.1.4, it mentions that Kaffe only supports "Interpreter", but not "just-in-time" for the PowerPC platform. Is this why the performance is rather slow? Is there any reason why Kaffe cannot support "just-in-time" for the PowerPC platform?
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 interpreter, check out the threaded interpreter patch at [1].
And of course, you could try either making the powerpc jit from janosvm 0.8.0 [2] work with Kaffe, or merging in the JITs from Mono, or libjit from dotGNU.
cheers, dalibor topic
