It is likely you can speed up Kawa quite a bit by fixing a few slow spots.
Specifically, anytime you do run-time reflection (or worse: eval/load) you're
going to lose a lot of performance. If you can replace generic arithmetic
or vector/list indexing with type-specific arithmetic/indexing that can
also make a big difference. List processing (especially if you call cons
a lot) is always going to be relatively expensive.
Profiling is probably the thing to try. I do little-to-no Java programming
these days, so I can't be any more specific with help.
