Remember that the autors of the Shootout refuse some changes to the code (like this one), to allow a fair comparison. The rules are strict. I have improved the Psyco version: http://shootout.alioth.debian.org/gp4sandbox/benchmark.php?test=nbody&lang=all If I find the time I'll try to speed up the Python version too following some of the suggestions of this thread. Note that on that site there are 4 different comparisons. The interesting question is how the Lua JIT can be that fast, it's often faster than Psyco: http://shootout.alioth.debian.org/gp4sandbox/benchmark.php?test=all&lang=luajit&lang2=psyco http://luajit.luaforge.net/ Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
