Maglev: Chrome’s New JIT Compiler

And Maglev is also an Ruby JIT [1] compiler

As a xoogler, I was thinking the same thing. I assume they knew from the get-go, because well, I can't see how they wouldn't. But I guess it doesn't matter all that much, anyway.

How devs can work with code that breaks at 80 characters in this day and age is beyond me.

Without the sites being JS heavy shouldn't everything be fast enough already?

This is a JIT for JavaScript...Why would you benchmark non JavaScript things.

Actually this concern is exactly why we built Maglev: A very fast JIT that can generate decent enough code very early so it can help even if you're not running tight benchmarks. In fact, the JIT by itself isn't particularly good at the traditional benchmarks yet. It's just very fast, and the code is most often good enough for real browsing usecases.

They do mention reduced power consumption in the opening paragraph. Usually executing the code you want to execute faster also translates to the CPU sleeping earlier again and this increased battery life.

I thought chrome was really popular on Macs? It’s on iOS where safaris rules.
