I meant: performance doesn't scale linear with cores. Provided graphs show big speed/core performance drop with bigger core numbers. Speed still rises, but we are wasting many cores and CPU power to get eg. just 20% speedup.

I think my question is- does z library engine scales linearly with core numbers? If we would be able to deliver raw video data at unlimited speed and just measure z performace, would processing speed be linear with cores rise?
