According to my tests on my F.Y.C clip (1280x720, 480 frames) aomenc right now has got roughly the same encoding quality @ bpp of 1 month ago, with a deviation within the 1%, but is also somewhere between 14-25% faster than 2 months ago for --cpu-used=4
Which means that clip now encodes, in single thread at CQ 20, in 66 minutes rather than 87 on my i7-4770.
