C++ Design Patterns For Low-Latency Applications

Performance optimizations remain crucial in applications like high-frequency trading (HFT), where low latency is essential. This post discusses a preprint article from Imperial College London focusing on design patterns in C++ for low-latency applications. The optimizations include common practices like prewarming CPU caches and advanced techniques like hotpath versus coldpath separation. Benchmarks using Google Benchmark demonstrate the effectiveness of these patterns, and the detailed implementations are available on GitHub.
