Hello,
I did few tests between the old version (2836) and the latest (2859), and ffmpeg is indeed slower.
We are talking about fps decimals but, since we enjoy every single increase, that's become significally important, I think.
Here's some logs:
1080p crf (first 2836 then 2859)

576p 2pass (first 2836 then 2859)

What you think?
Thanks in advance
