For several years now we’ve tracked192 the fact that, over time from 2012 onward, Android JavaScript performance has become wildly divergent from iOS JavaScript performance. And not in a good way.
To give you an idea of how divergent it has become, try:
- http://emberperf.eviltrout.com671
- Complex list
- Ember 1.11
This is the benchmark most representative of Discourse performance, and the absolute best known Android score for this benchmark is right at ~400ms on a Samsung Galaxy S6. That doesn’t seem too bad until you compare..
- iPhone 5 ? 340ms
- iPhone 5s ? 175ms
- iPhone 6 ? 140ms
- iPad Air 2 ? 120ms
- iPhone 6s ? 60-70ms
In a nutshell, the fastest known Android device available today — and there are millions of Android devices much slower than that out there — performs 5× slower than a new iPhone 6s, and a little worse than a 2012 era iPhone 5 in Ember. How depressing.
