In this episode, Jean Boussier and I dive deep into performance optimisation for Ruby on Rails applications. From diagnosing common bottlenecks and mastering advanced caching techniques to leveraging YJIT, jemalloc, and server concurrency models, we explore practical strategies for scaling apps efficiently. We also discuss key metrics for monitoring production performance, cost-effective observability, and modern Rails patterns to embrace or avoid. Perfect for developers looking to take their Rails performance game to the next level!
