I'm sure, but luajit wins handily over all the scripting interpreters. I'm not much concerned with ruby in particular. I'm suspicious that luajit is constrained in features. I doubt you can dynamically load in object code for modules, for example. This makes it not quite a straightforward comparison to the other interpreters.

Actually, this is incorrect. LuaJIT is explicitly compatible with the standard Lua ABI for modules.

Since it is able to use certain non-ANSI C features on the various platforms it supports it can do other neat things like enable coroutine calls across Lua/C stack boundaries.
