Which fast-ruby advice holds on your Ruby?
Every benchmark names the idiom it claims is fastest. We run each one on every Ruby, with and without the JIT, and check whether the claim still wins on that Ruby.
Some benchmark jobs in this run failed. Their results are missing, so a result shown as skipped may be a crash. Check the CI run for the failed jobs.

Each dot is one Ruby, from 2.1 to head, then JRuby and TruffleRuby, that has the build you picked. The dot with the dark ring is the Ruby you selected, . Hover a dot to see which Ruby it is.
