But my post was just tongue-in-cheek

Code:sudo do-release-upgrade
Probably not useful for testing/comparing purposes as it won't be a "clean" install, but for those of us with Ryzen 3000 series CPUs and a need to run a 5.x series kernel, this will work.

Which means it relies upon what ffmpeg buildsystem detected vs what was overriden (not a lot, see table on first page of article).
And actually uses different archive for Windows, it could be prebuilt for Windows as no Windows compilation flags are listed on first page. Therefore this test might be misleading, as it might neither compare out of the box performance (if Ubuntu packages are not used) nor real OS performance (in which case software would be compiled with the same flags on both OSes).Last edited by reavertm; 26 July 2019, 12:58 PM.

Michael, I can't believe it. Please don't use BLAKE2 for cross-OS comparisons, and instead PLEASE do use it in cross-processor ones.
"Cycles Per Byte" means it is supposed to compare processor architectures, NOT operating systems. If the results vary, it's caused by kernel differences or compiler differences (unless the whole program has been written in assembly, which is likely).Last edited by tildearrow; 26 July 2019, 01:35 PM.
