Do you have a particular task in mind? The languages have different semantics and that has an effect on performance. E.g., in Ruby nearly everything is a method call. Ideally a JIT would eliminate that overhead, but you'll likely see varying degrees of performance depending on what your task is. And that's before you get to core library methods, which often are written in C and not handled by the JIT.
