I think it's on a right track to be quite something, which is why I wanted to try it out & mention that on HN. It's interesting to note that on the "classic" Ruby, there is work ongoing in 2.6 to accelerate it quite a bit (MJIT). The current PR for this is there: https://github.com/ruby/ruby/pull/1782 https://github.com/ruby/ruby/pull/1782 Even before that, Ruby is getting faster, you'll get running times from 2.0.0 to 2.5.0 for a little benchmark I made here: https://github.com/thbar/kiba-ruby-benchmarks https://github.com/thbar/kiba-ruby-benchmarks
