Benchmarking a Go AI in Ruby: CRuby vs. Rubinius vs. JRuby vs. Truffle – a year later
After a first run ~13 months ago I thought it was time to do a new run and see how fast our contestants have gotten since the last time! especially now that Ruby 3x3 is a thing, it asks the question how much faster are the different implementations as compared to the Ruby 2.0 baseline. Included Rubies are TruffleRuby, CRuby/MRI, JRuby and Rubinius. Check out more in the blog post!
