btw, i really wonder thy why want to bechnmark fflmpeg with your tiffs if
your "software will output to jpegs" :-) internally ffmpeg with convert
your tiffs anyway. convert 20s of your tiffs to jpegs (imagemagic batch),
leave threads to 0 and si if ffmpeg will be faster. and next try mjpeg

20k frames are a mere 800s of a 25fps movie... how slow is cpu process ?
afaik nvenc can only do mjpeg_cuvid for stitching images, it won't work with
tiffs...
e.g. ffmpeg -vsync 0 -hwaccel cuvid -c:v mjpeg_cuvid -framerate NN -i
image_%04d.jpg -c:v
