Message in a bottle, by Konstantin Haase

What does really happen when we call a method? How do the different Ruby implementations actually figure out what code to execute? What plumbing is going on under the hood to get a speedy dispatch? In this talk we will have a look at the internals of the the major Ruby implementations, focusing on their dispatch. From look-up tables and call site caches, to inlining and what on earth is invokedynamic? Fear not, all will be explained! Barcelona Ruby Conference is a conference held by Codegram.
