It is generic, but the graphs on arewefastyet.com suggest that it isn't actually making most regular benchmarks go faster, just some of the asm.js-style ones.

It makes one or two of the Octane benchmarks faster, like Mandreel. But Mandreel is quasi-asm.js as well.

A powerful JIT like LLVM will tend to do best on large long-running benchmarks, like asm.js.

Well, that would make sense as asm.js is just a formalization of what the optimizing compilers were doing with LLVM transpiled JS code: http://mozakai.blogspot.com/2013/06/what-asmjs-is-and-what-a...
