Concurrency in Ruby: Threads, Fibers, and Ractors Demystified

Speed up your Ruby applications with the power of concurrency! Join us as we demystify threads, fibers, and Ractors, understanding their unique strengths, use cases, and impact on Ruby performance. Learn to tackle I/O bottlenecks and enable parallel execution, boosting your code’s speed.

For a very long time, Ruby had limited options for concurrency, mainly relying on threads, which developers often dreaded. However, with the exciting updates introduced in Ruby 3.0, the fiber scheduler and Ractors provided a remarkable 3x performance boost. Despite these advancements, few have used these features in production. But now, we can confidently say that they are ready for use.
