Every few seconds the screen freezes for a fraction of a second. This happened to me on both Chrome and Firefox.

I suspect the lag is caused by garbage collection taking too much time. I ran into a similar issue on Firefox when working on my canvas game. Not sure how this can be fixed. (fwiw, I am running on this on an i5 Macbook Air)

Yeah, I'm seeing the same regular stutter as well. I noticed that it was reporting 50fps, but I suspect it's running at 60 fps with vsync and then dropping 10 frames every second.

On Firefox, the profiler tool will show you garbage collection in red. For me, there are pauses too, but they are not caused by garbage collection.

I'm not sure how they are scoring but FPS is the wrong measure for perf in WebGL. The browser locks the refresh rate to the monitor refresh rate, usually 60hz. Rather than FPS you need to measure the amount of work you can do before the framerate drops.
