Towards Ruby 3x3 performance

Ruby 3x3 project has a very ambitious goal to improve MRI performance in 3 times in comparison with MRI version 2.0.

This talk is about my attempt to achieve this goal in a project to implement RTL VM instructions and JIT in MRI VM. The project can be found on

We will talk about the project motivation, goals, and approaches, and the current state of the project. Performance comparison with JRuby, Graal/Truffle Ruby, and OMR Ruby and future directions of the project will be given too.
