@ ajaksu2 > Applying your patches makes no difference with gcc 4.2 and gives a > barely noticeable (~2%) slowdown with icc. "Your patches" is something quite unclear :-) Which are the patch sets you are comparing? And on 32 or 64 bits? But does Yonah supports 64bits? IIRC no, but I'm not sure. I would be surprised from slowdowns for restore-old-oparg-load.diff, really surprised. And I would be just surprised by slowdowns on reenable-static-prediction.diff. Also, about ICC output, we still need to ensure that it's properly compiled (see above the instructions for counting "jmp *" or similar). In the measurements above, ICC did miscompile the patch with the switch. By "properly compiled" I mean that separate indirect branches are generated, instead of just one. > These results are from a > Celeron M 410 (Core Solo Yonah-based), so it's a rather old platform to > run benchmarks on. Not really - at the very least we should listen to results on Pentium 4, Core (i.e. Yonah) and Core 2, and I would also add Pentium3/Pentium M to represent the P6 family. Anyway, I have to do my benchmarks on this, I hope this weekend I'll have time. _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4753> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
