Steven D'Aprano>Very slow to do what, compared to what? The decay time of the tau meson?<
Probably every answer I can give you is wrong for you, so answering is almost useless... In this thread we have already given the most pertinent answers to the original question from Diffuse. I can show you this page, but I think this is useless too for you: http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=python&lang2=ocaml And, by the way, this is false: Robert Hicks>Python is fast enough for just about anything you want to do with it.< If you are on a Unix-like OS, then the page about Weave from SciPy can show you that sometimes Python isn't quick enough.
