V8 hasn't implemented asm.js AOT because the authors claim not to need to; but if you compare the performance of a Unity3D WebGL export vs FireFox the gap is very wide.

Well, each has its tradeoffs. JIT has low startup time, whereas Firefox will spend quite a while compiling before anything actually happens.

For the content I'm describing, FF has vastly superior startup/cold execution performance, and mildly better long term.
