For raw speed in TeX, you will never do better than well-written
primitive code. The problem is looking after the code or for the
non-expert! (Look at Bruno's FPU or regex code: all as fast as it can
be, all *very* hairy to read.) And of course if one *knows* you are tied
to LuaTeX then some things will be faster/easier in Lua.
