I got 2,996 in Firefox and 1,277 in Chrome (2013 MacBook Air 13").

Interestingly, Chrome had much worse performance for float32 than float64... yet Firefox had slightly better performance. I guess the Chrome team implemented Math.fround yet none of the optimisations which make it useful!

I got a 4,690 on Firefox Nightly so there's so big improvements coming down the pipeline.

I got 3,115 in Firefox Nightly. That's a slight improvement over the 2,996 in normal Fx, but not that big, really.
