Note that you should not choose Ember if you are creating an app intended to be used on mobile, as it doesn't yet have code-splitting. This talk explains about why this is a hard requirement: https://www.youtube.com/watch?v=4bZvq3nodf4
It isn't just worse on Android it is BRUTAL on Android.
I was deeply unhappy with the 3x-5x widening iOS and Android JavaScript perf gaps through 2014 and 2015 (TL;DR Qualcomm has completely lost the plot) but in 2016, it's.. even worse.
The good news is, Ember 2.10 looks like a major speed improvement! The bad news is, Android is still 10x slower with Ember.
That doesn't help much. Server rendering means the user can see something, but if the browser is executing a 2mb blob of JS and it takes 3 seconds to do so you get major jank.
