Ruby 2.6.10 was consistently outperforming all new Rubies on.

Recently I had been going through some of the old benchmarks in the Ruby Great Implementation Shootout from around 2010.As an experiment, one night I ran the benchmarks against Ruby 3.2.0, Ruby 3.2.0 --yjit, TruffleRuby, TruffleRuby GraalVM, and Ruby 2.6.10.Most results were as expected. However there was a benchmark that Ruby 2.6.10 was consistently outperforming all new Rubies on.
