Part 1: Basics
This is the part of the book that lays the foundation for designing and building your application for low latency.
Chapter 1 defines latency, explains why it matters for user experience and system efficiency, and distinguishes it from bandwidth.
Chapter 2 covers essential modeling techniques, such as Little's Law and Amdahl's Law, explains latency distributions, and teaches you how to measure and visualize latency in your systems properly.
When you've finished with this part, you're ready to read the rest of the book.
