float[] is super slow

Hi, 

the problem is that it is too slow compare to Float32Array.

Especially it is super-slow it everything except chrome: FF, IE\EDGE.

More then that, it produce tonns of garbage (in FF and EDGE) working with large images: 

Here I wrote some float[] code to emulate water surface

Also, it is super hard to calculate large terrain, geometry arrays, e,t,c.

There is an ugly workaround (which breaks portability, yes I write portable client code (iOS, Android)):

public static native float[] createFloatArray(int size) /*-{
    return new Float32Array(size);
}-*/;

Can google GWT team make a compiler setting or option to use platform arrays instead of JsArray ?

This is a really huge performance impact !

Thanks
