CppNorth, The Canadian C++ Conference 2025

Get ready for a crazy fun & informative talk! Boost your C++ code's performance by utilizing the full power of your computer’s built-in cache. In this talk, we'll delve into the basics of caches, spatial and temporal cache locality, and practical techniques for optimizing cache access. We'll also explore cache prefetching, branch prediction, and false sharing, providing examples modelled on real-world production code and performance benchmarks to drive home each point. By the end of this talk, you'll be equipped with the knowledge and tools to better optimize your code for cross-platform performance gains.
