--- Comment #38 from caulier.gil...@gmail.com ---
My last comment:

Under My Windows 10 64bits running on VirtualBox with 4 cores, HEIC encoding
use only... one core...

Encoding is not parallelized. This is why it's so slow.

Encoding a Canon EOS-R (30 Mpx) CR3 raw file (16 bits color depth) to HEIC 
(lossy compression) took... 45 seconds.

But it work...

VoilĂ . So for optimisation and improvement, all must be delegate to UPSTREAM
libraries as said in comment #36.

I close this file now.

Gilles Caulier
