We often rely on concurrency in Ruby without really understanding how it works under the hood. In this talk, we’ll build a simple TCP server and iteratively improve it using processes, threads, and fibers, measuring along the way. By connecting these primitives to real-world servers like Puma, Falcon, and Unicorn, you’ll come away with a clearer grasp of how Ruby handles concurrency and the tradeoffs behind each approach.
