New issue 4402 by [email protected]: Atomic Web Player slowness
https://code.google.com/p/v8/issues/detail?id=4402
This game:
http://docs.atomicgameengine.com/webplayer/physicsplatformertest/
runs more slowly in Chrome than Firefox. Profiling it, the _longjmp method
is very high in Chrome, eclipsing the rest of the code, while in Firefox
it's fairly high in the profile but far less significant.
_longjmp is how Emscripten implements longjmp(). It calls out of the asm.js
module to normal JS which stores the value and then throws a JS exception.
This unwinds the call stack until a previous setjmp catches it, which also
called out of asm.js in order to do a try-catch (using the invoke_*
methods).
In other words, there is significant asm.js/non-asm.js interaction here.
Perhaps this is stressing TurboFan/CrankShaft interaction?
