I've been experimenting using CSS3 translate3d transform for moving
the layer container div when panning. My experimental code is in the
elemoine/accel3d sandbox.

I would appreciate if IOS users could test [1] and [2] and report
back, to know if my "3d-accelerated panning" code makes a difference.
I'm also interested in feedback from Android users, although I don't
expect better results with ?accel3d, since, to my knowledge, Android
doesn't support 3D acceleration in the browser.

(this one may yield a better map drag/pan experience in IOS/Safari)
