Vlad's tests were on a desktop machine. We should do experiments on a mobile
device and report back. However, I see no fundamental reason why the
observed closeness in performance between JS and C would be unattainable in
lower-end devices. Our ARM backend is less mature but that will improve.

What are your target platforms, specifically? Anyway, we need to plan for
the future, and it seems safe to assume that JS optimization techniques will
spread to every platform where they're useful.
