Device rotations suck (especially on Adreno GPUs)
Currently when one rotates the device on very simple pages (about:mozilla) or about:privatebrowsing, there is a whole slew of resizing and work going on and what the user sees is very noticeable and jarring. http://mozilla.org is another good example; our rotation and repaint looks poorly and is slower compared to Chrome
Nexus 4 Adreno 320; really slow Samsung Galaxy III; kind of slow Samsung Galaxy Note; slowish
A big part of the slowdown is likely the reinflation of about:home, which we do all the time - regardless of whether about:home is actually visible. Bug 838793 removes the about:home view when it's not being shown, so it's worth keeping an eye on that to see if it fixes (or at least helps) this bug.
not tracking on the assumption that bug 838793 mitigates

I tried the fix/APK in bug 838793, on my Nexus 4 and Note but couldn't determine if there was any difference between Nightly and it; I just used about:mozilla and rotated back and forth and it looks the same to me.

Even google.com's empty mobile page is super slow. Go to google.com and rotate it. You'll still see that huge 1-2 second lag (on a quad-core phone with an Adreno 320 GPU).
