New issue 3080 by [email protected]: Bad asm.js performance (stalls)
http://code.google.com/p/v8/issues/detail?id=3080

I am in the process of porting a large in-house game engine to emscripten+asm.js.

I made a test using a platformer demo, which uses a custom physics engine and renders using WebGL. It runs absolutely smooth, 60fps in Mozilla Firefox.

However, in Chrome/V8, it runs fast but has regular stalls, as if it was JIT compiling different codepaths all the time. I run this on a Athlon X2 from 2007.

I would expect it to run as well in Chrome/V8 as in Firefox, or at least expect it to be playable.

Here is the link to it:

Thanks!
