Some numbers for folks to examine based on 3x test of each state:
Non-fullscreen: 4094.5ms (test average) Fullscreen: 10528.2ms (test average)
Non-fullscreen: 4094.5ms (test average) Fullscreen: 10528.2ms (test average)
I've re-done the tests for the iPad. Mobile Safari javascript is more than 2x as fast when run in the browser versus fullscreen mode.
