Concurrency in Ruby - From fork() to Fiber

Explore Ruby's concurrency mechanisms in this 26-minute conference talk that demystifies how concurrency works under the hood. Build a simple TCP server from scratch and iteratively enhance it using processes, threads, and fibers while measuring performance at each step. Learn how different concurrency patterns connect to real-world Ruby servers like Puma, Falcon, and Unicorn, gaining practical insights into the tradeoffs between various approaches. Understand the fundamental concepts behind Ruby's concurrency model through hands-on examples that progress from basic fork() operations to advanced Fiber implementations, providing you with the knowledge to make informed decisions about concurrency patterns in your own Ruby applications.
