Ah yes, by the way: I also ran manually performance on speed.python.org yesterday: it added a new dot at Feb 25. > In the results, 9 were marked as > "significantly" different between the two commits.. 2 of the > benchmarks showed a marginal slowdown and 7 showed a marginal speedup: I'm not surprised :-) Noise on micro-benchmark is usually "ignored by the std dev" (delta included in the std dev). At speed.python.org, you can see that basically the performances are stable since last summer. I let you have a look at https://speed.python.org/timeline/ > | Benchmark | speed.before | speed.after | Change > | Significance | > +=========================+==============+=============+==============+=======================+ > | django_template | 177 ms | 172 ms | 1.03x faster > | Significant (t=3.66) | > +-------------------------+--------------+-------------+--------------+-----------------------+ > | html5lib | 126 ms | 122 ms | 1.03x faster > | Significant (t=3.46) | > +-------------------------+--------------+-------------+--------------+-----------------------+ > | json_dumps | 17.6 ms | 17.2 ms | 1.02x faster > | Significant (t=2.65) | > +-------------------------+--------------+-------------+--------------+-----------------------+ > | nbody | 157 ms | 161 ms | 1.03x slower > | Significant (t=-3.85) | (...) Usually, I just ignore changes which are smaller than 5% ;-) Victor -- Night gathers, and now my watch begins. It shall not end until my death. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
