"Every benchmark on that page is faster for PHP"

Let me advice you to benchmark it "accuracy" on your machine setup, don't rely what is on that page.

Make sure the error with --jit-verbose=1 which will show whether it uses MJIT correctly.

ruby --jit-verbose=1

Ruby 2.6.3 6:22.00s

As for mine, Ruby slightly faster 4:05s - 4:09s which is close to PHP in timing.
