I'd wondered if there'd be anything to gain from doing = that, but stopped short of actually trying it myself. I'm glad to see = someone else has tried it, even if the conclusion from the experiment = was that it wasn't worth folding in. Actually, I'd been thinking about = converting byte-code to C, changing stack slots to register variables, = that sort of thing, and turning GCC's optimizer loose on it, but I doubt = it'd perform all that much better than the JIT version if the primitives = were dominating. Thanks for the links! Ken=
