My understanding is that virtualization overhead is not a
OK, I've placed on http://www.aleax.it/Python/ the files that pybench writes (with the -file option) for each machines, the names are onmbp.txt and onwin2k.txt -- just 20k each (I'm not sure their format is documented, but I guess that, worst case, one just needs to study pybench's sources). > builder knew about, etc. I think Apple switched to the Intel compiler for > x86 macs, was python built with that or with gcc? The compiler Apple distributes freely is still gcc -- the intel compiler (rumored to have better optimization) costs hundreds of dollars, so Apple couldn't possibly distribute it for free with XCode. > In short, your results are interesting but I'm not sure what to make of > them yet. Consider me available if you need some other tests and don't have other easy access to OSX and Windows running on the same HW. Alex -- http://mail.python.org/mailman/listinfo/python-list
