This new version of the patch improves performance by up to 135% on Graviton2 Arm64 and by up to 95% on Intel. Compared to the previous version of the patch, there is more uninterrupted work per thread that results in better performance. Please let me know how I can improve the patch. There are other functions (lum_convert and chr_convert) that may benefit from multi-threading. I have not seen these functions appearing on a hot profile. Is there a benchmark for those functions? Thanks, Sebastian
