this is very interesting. Is the PBC VM already working? If so, how do its performances compare against the normally compiled code? I and Niko did some benchmarking on pypy-jvm and we discovered that we spent (unsurprisingly) the largest amount of time inside the main eval loop (up to 68% of the total on some benchmark, IIRC). On average, the dispatch overhead is something like 50%. Is it the same for jython? Btw, did you consider the possibility of reusing the pypy eval loop instead of rewriting yet another one from scratch? ciao, Anto _______________________________________________ [email protected] http://codespeak.net/mailman/listinfo/pypy-dev
