And yes there are situations where it will be viable and even recomended to use more threats than cores but which situations is a much longer answer without upper bond :) | |

There is no such thing as a 'controlled benchmark experiment' — you can establish a few baselines, sure, but real life will always be different from what you can assemble in a lab. | |

| Sep 9, 2020 at 9:49 | comment | added | Yves Daoust | @qwr: another great truth is that benchmarking is terribly difficult. In particular when developing general purpose solutions such that you don't know the problem size and specifics in advance (and sometimes even have no idea of realistic problems). Some understanding of the trends in behavior is not luxury. | |

| Sep 3, 2020 at 7:43 | comment | added | qwr | This answer contains a great truth: benchmarking beats lots of theory and speculation. | |
