Cache-Friendly C++ - Jonathan Müller - CppCon 2025

The podcast features a presentation on cache-friendly C++ programming, detailing how CPU caches work and how to optimize code for better performance by considering memory access patterns, data sizes, and avoiding false sharing in multi-threaded applications. The speaker discusses various techniques such as using smaller data types, reordering struct members, and data-oriented design to improve cache utilization. Following the presentation, the speaker addresses questions from the audience, clarifying points about thread safety, branch prediction, cache behavior, and memory layout, while also acknowledging edge cases and the importance of benchmarking to validate optimizations.
