Whatever your definition of significant, I don't think the figure I have is. It's around 1% on a dual core system on average, but that's near the measurement error on the other hand. I'll probably be able to provide figures for systems with more cores within a few days. Another possible comparison point is the impact in openhevc. I've heard it is more than 20% faster per core over ffhevc, therefore I'd expect such things to cause a bigger impact. Technically, I wager hevc and vp9 are different here. hevc has a second level of filtering called sao, that causes a delay of one CTB line/64 pixel lines. So, effectively, parsing and pixel output are probably farther apart than in vp9.
