From what I've seen, SIMD.js does make doing some calculations quicker, although it's not the 4x increase one might assume. It's more like 30% to 50%. The latency and overhead associated with moving the SIMD.js calculations into a Web Worker actually reduces the performance increase to as little as 10% to 20%.

While message passing might make sense for some tasks, it's not going to be quick enough to do things in 16ms and achieve the magical 60fps. Eventually shared memory is going to be needed, and if we get that far I think there will have to be some sort of acknowledgement that these performance-related features can't possibly be foolproof.

Oh, and an asynchronous thread safe DOM, please and thanks :)
