Nitro Javascript engine? It could be an important difference between this test and FB's app. Safari gets it. It seems ambiguous still whether UIWebView users get it.

A more apples-to-apples comparison would be to put it in a iOS app running UIWebView and see if the performance is maintained. I'd certainly be interested in the results.

It's not ambiguous. On iOS, only Safari can JIT JavaScript. This is because Apple doesn't trust your app enough to let you made code pages. It also doesn't trust the app it makes when you install a web app to your home page (and it's not just a Safari bookmark).

I suspect the latter may change, but I wouldn't count on the former.

Performance is also great in a wrapped version. The bottleneck we had to solve was in event management, the GPU & compositor not in the JavaScript execution.
