Than MRI Ruby you mean.

The advantage wouldn't be as much if Ruby designers cared to add AOT compilation in the same vein as Dylan or Common Lisp to the canonical implementation.

That's exactly the space that Crystal [0] seems to be exploring. Statically type checked and pre-compiled via LLVM. So it isn't the Ruby designers themselves, but definitely Ruby flavored.

Given the nature of orders-of-magnitude comparisons and the lack of Ruby implementations that are even one order of magnitude faster than MRI, "...than Ruby" is reasonably accurate if "...than MRI Ruby" is at all accurate.

Maybe, though that's unproven. AFAIK, actual Ruby implementations with AOT only seem to gain about a factor of 2 improvement, not an order of magnitude.
