The goal of Ruby v3 is to be 3 times faster than v2.

Unclear if that goal has been achieved.

From benchmarks [1], 2.8.0 (with jit) is ~2x faster than 2.0.0p648 [2].

notice the "3x3" goal is on a specific benchmark (optcarrot), not on all workloads.

There's no such thing as a performance measurement "on all workloads".

A lot of focus has been on this benchmark https://github.com/mame/optcarrot/ It has seen huge performance improvements thanks to the mjit but not quite 3x yet.

Not up-to-date but many more ruby 3x3 articles, see https://planetruby.github.io/calendar/ruby3x3

Performance is more of an implementation level change rather than a language change unless they are restricting the language to facilitate new optimisations.
