Gutsy move indeed. Though I wonder, what was the development cost in real life cash for gaining those 5% of performance?

3 months. Two people working on it (me and @awfulben).

Out of curiousity, did you look at improving LLVM compile times? I didn't get that out of the article.

Awesome write up btw.

As Phil said, the development cost was not that high all things considered. But even if it was - think about the number of user-hours that 5% is leveraged across, and the resulting time savings and battery life savings for those users. It would be worth investing even more than we did for 5%!

Considering there are now 1Billion Active iOS devices, that 5% saving is huge!

I wonder if this will make in time for iOS10.
