Unfortunately it had not improved Rails application performance while it achieved a good progress on some other benchmarks. Beyond the progress at Ruby 2.6, JIT development on Ruby 2.7 will be dedicated to improve performance of real-world applications, especially Ruby on Rails. Come and join this talk to figure out how it's going well and what you should care about when you use it on production.
