Thanks for the extra results. Obviously, a single micro-benchmark will only take you so far (and something like the Computer Language Shootout gets you farther -- it's a shame and mystifying (to me) that that site no longer has results for LuaJIT...).
But anyway, in my (limited) experimentations with LuaJIT, it's often been within a factor of 2x-3x of speed of C, which to me is pretty fast, and typical of many statically-typed, compiled languages.
