That's interesting, I will have to give it a deep dive to understand what is happening deep down before I can validate though |

Hi, could you provide some example code + media that illustrate the performances gap ? I would like to try and reproduce and see how pr #2490 influence this. |

Helps with performance in #2395 test to some extent.
If you check the
ndarray.flagsof certain frames, you see thatOWNDATAandC_CONTIGUOUSare sometimes false, which I think is slowing down something in PIL a lot. The copy is improving performance on the #2395 test by about 3x for me, on OS X ARM.
