But I couldn't detect a speedup for either float or int in bench.py. Also, in perf.py I'm consistently getting slower results for float with the patch. > there is a clear need, of course I can look into that and add these > derivatives (as I said, there are still some 40+ opcodes unused.) I'd say that the minimum requirement for a performance enhancement patch is that there aren't any slowdowns. :) I'm getting a 9% speedup for mandelbrot and an 18% speedup for spectralnorm. That's nice, but many benchmarks that Antoine and I have posted show slowdowns of 15-18%. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14757> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
