It is often said that C++ is a great language for low latency systems, such as finance, audio processing, and video games. But what exactly do we mean by "low latency"? How is that different from "high performance"? And what makes C++ a great language for that? This talk is an attempt at answering these questions. We will look at low latency use cases across these different industries, establish their commonalities and differences, and discuss typical challenges in low latency systems and C++ techniques to overcome them.
