Ruby 2.6 Preview Rolls Out With JIT Support

[ksec]

People often mixed up Rails and Ruby. Rails is definitely not as popular as it was, but Ruby is doing OK. BTW Ruby 2.6 is already faster then Ruby 2.5, without the JIT.

Github ? Gitlab ? Discourse ? All of them are Ruby Rails.

In fact, I love the approach: adding a "JIT" (it is technically a JIT, but a very clumsy way to do it for some people hoping for an "online" compiler). Probably, a "JTL" compiler will really make wonders in future (JTL means to compile the bytecode which was already ran in a big library, so it will speedup loading and code generation).

For people reading the presentation, I am surprised that they could JIT anything in less than 700 lines(!) and get even some speedup.
