Performance Loop - A Practical Guide to Profiling and Benchmarking

Discover how to optimize code performance effectively in this conference talk from NDC London by Daniel Marbach. Learn the systematic approach to performance optimization through the "performance loop" methodology. The presentation covers how to identify high-value optimization targets, isolate code for accurate measurement, implement a reliable benchmarking process, and develop performance awareness without falling into unnecessary optimization traps. Master practical techniques for profiling code, creating meaningful benchmarks, and verifying that your optimizations actually improve performance rather than degrading it. Essential viewing for developers who need to ensure their code performs well at scale while avoiding common pitfalls of premature or misguided optimization efforts.
