Nobody really wants native code programs these days. Native performance scares them. If you compare those numbers to the OpenCL benchmarks with Intel CPUs, emscripten / asm.js is like buying a $350 CPU (i7 7700k) and executing programs like you had a $60 CPU (Pentium G4400). What a great way to waste power.
What I've found is the following:- the i7700k ~ 2.6 faster than the pentium - http://cpu.userbenchmark.com/Compare...00K/3539vs3647
- native clang is about 1.3 times faster than wasm - https://hacks.mozilla.org/2016/10/we...owser-preview/

native: 6.5 seconds
Under Chrome without SIMD.js it took 18 seconds
With Firefox, also without SIMD.js, it took about 11 seconds
With Firefox Nightly using SIMD.js and EmScripten building their SSE2 code yielded a time of about 15 seconds.
1.3 times? ok. Nice job cherry picking one synthetic result, where it doesn't suck.

The references I cited were composed of many more tests than a single example of unknown code quality.
However, please take a look at the article Michael released today that includes the pentium and i7700k.
Feel free to share more thorough benchmarks in that thread.
