Just a heads-up that I just pushed bug 1157746 to inbound, which enables async scrolling for trackpad/wheel scrolling by default for nightly OS X desktop builds. It requires e10s, and so if you have e10s disabled it has no effect for you. If you have e10s enabled, you should see smoother/more responsive scrolling, and probably more "checkerboarding" (scrolling into unpainted content areas).
Note that this is currently NOT riding the trains, we will leave it enabled on Nightly only until it is more baked, but it should be stable enough for general usage. Bug 1178298 tracks letting it ride the trains. Please file bugs in the Core::Panning and Zooming component if you see anything misbehaving. If you need to turn it off for whatever reason, you can set the layers.async-pan-zoom.enabled pref back to false. Assuming this doesn't get backed out, I intend to also enable the same thing on Windows in the next day or two (bug 1157745). Linux will take a bit longer since there are some test failures we need to sort out first.
