Phoronix: Icculus: EmScripten Audio Conversion Performance In The Web Browser

Linux game porter and SDL developer Ryan "Icculus" Gordon has shared some performance measurements when bringing SDL's new audio conversion support within web-browsers using EmScripten...

EmScripten scares me.

Why? It's an interesting project. Should help for example compiling Rust into WebAssembly.

This would be awesome!

Speaking of WebAssembly, I'd much rather see this test when converted to that rather than JavaScript.

I agree that it is interesting. It's just the
"Take a C/C++ program and turn it into javascript to run in a browser. What could possibly go wrong?" that scares me.

Emscripten converts to asm.js, which is a subset of JavaScript pretty similar to WebAssembly (infact, WebAssembly was inspired by asm.js).

Well, it's already been done with several large projects and it's worked pretty well (see Unity, Unreal Engine, etc.).

It's not fully ready yet, but Emscripten already has experimental support for WebAssembly target, and Rust input. See:

Yes, what I was trying to say is that the result of Icculus' benchmarks are not about pure JavaScript, but of something really close to WebAssembly.

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.
