@anon: I see discussions all the time on doom9, avsforum and other video enthusiast forums about which builds to use for speed; whether to use 2.5.8 or 2.6 and which builds within those versions to use.
I had requests for months to compare them and I finally found the time to do it.
Since most people don’t care which version they use – they just want the most stable and fast – this is a relevant test.
Plus the MVTools2 tests compared the exact same versions but just different builds.
