I hear the Truffle+Graal combination is getting very good results about Ruby. Here is video about it (pointed to the missing-method example): [1]

They're hitting 35x in some benchmarks [2]. Most benefits being in workloads where Ruby has to continuously talk to C; the result-passing part gets compiled away.

It is available in Java 9, if I'm not mistaken. LLVM IR bytecode ingestion is in preparations too [3].

Three of the biggest Rails Shop, ( this is assuming the most popular, resources heavy usage are Rails related. ) all run on CRuby. That is Cookpad, Shopify, and GitHub. ( Basecamp in rather small compared to these 3 )

I wonder if there are any popular webshop ran on JRuby, or why those three dont use JRuby.
