So there's one fibonacci sequence benchmark that's faster? Come on. The issue with Ruby is that the things that make it so nice (all of the great object model and meta-programming additions) also bring a certain level of overhead. If it was such a simple task to optimize then the MagLev guys would have produced a kick ass speedy Ruby years ago, based on all of the things that they know about Smalltalk VMs. That said, if Apple has the resources to make MacRuby as fast as Objective C then holy crap; I'd be on that like white on rice. I don't believe for a moment that Apple would ever use Lua as their systems language of choice; more that I personally thought it would be a great pick. As much as I love Ruby I seriously doubt that Apple would ever be able to squeeze the required performance out of it; the language itself is the problem, not the implementation. Look at all of the work that's gone into producing fast Ruby VMs over the last several years . . . Really, there's low hanging fruit out there and Ruby just doesn't make sense in this context.
