Hi,

I'm the Manager of the Ruby and Rails Foundations team at Shopify.

We are investing a lot on R&D for CRuby as well.

We have 6 people working full time on Ruby implementations, both CRuby and TruffleRuby. Not only Chris Seaton is here, but we have two CRuby Core members as part of the team, Aaron Patterson being one of them.

Surely this would reflect in benchmarks? Perhaps there is an even slower aspect of the language manifesting in JRuby....

Is this supposed to reflect in Ruby’s favor? Self was built to be performative in spite of its novel features—the slow aspects of the language were never encouraged to take a central role. A better equivalent might be applescript or bash or a language that emphasizes some particular quality of expressiveness.
