It's factorial(), so it's handling large "longs". So it's about 2x as slow as CPython. End of the story. Just to be sure, before digging into bytecodes you generate, try to compare the pure Python versions of factorial. The PyPy one is twice as slow as the CPython one because it's all about large "longs". A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
