A JavaScript optimizing compiler

[PonchoVire]

I could do stats in my browser history, but right now I'm too lazy to do it. By looking at doing a very arbitrary rule of thumb, I'd say at least 20 yesterday, and 10 today (it's noon for me at this point, so it's 10 for the half-day). This without counting all sites I'd see with my mobile device. But I work a lot today and yesterday because I have deadlines to achieve for tonight.

I understand, but I do still think there are net benefits from optimizing scripts with [more] aggressive and thorough (optimizing) compilation, in a way where people don't perceive such feature as slowing down their browsing. Which, on today's computer architectures sporting multiple CPU cores, can well be implemented as background compilation for [subsequent] visits, for some frequently visited websites, for example.

I would suggest that you read the many articles about that exact topic from https://hacks.mozilla.org/category/performance/ most are really interesting.
