Ruby 3x3 announced that Ruby 3.0 would be three times as fast as Ruby 2.0. It was an audacious goal, especially for a language released in 1995.
Ruby 3 is due to be released in less than a month. They’re hard at work on some of the features, but non-JIT performance is pretty close to release speed. If they pull another 5%-10% speed increase at the last minute (which happened for Ruby 2.5!) it’ll be surprising. The current performance is basically the “real” Ruby 3 performance.
