> Just fix the VM then No the point isn't that the VM is broken. The point is that the Ruby language has semantics and is used in idioms that nobody knows how to optimise well yet. > tinyrb based on potion based on lua with classes is ~200x faster in method calls tinyrb is interesting, but it just isn't the same semantics as Ruby: https://github.com/macournoyer/tinyrb#what-wont-be-in-tinyrb... tinyrb doesn't have a better VM - they're implementing a different programming language with all the hard bits left out! In my project we've been having to do new original research into how to optimise Ruby - introducing concepts such as dispatch chains which haven't been needed more because people don't try to push metaprogramming in most language like they do in Ruby. http://stefan-marr.de/downloads/pldi15-marr-et-al-zero-overh...
