Practical techniques for delivering low latency software.

From first principles to production-ready code, "Latency" teaches you how to make your software faster at every layer of the stack. You’ll learn what latency really is, how it differs from bandwidth, and why it matters for user experience. Then, guided by practical examples, you’ll apply Little’s Law, design lock-free algorithms, and architect caching systems that scale. You’ll discover how your code runs differently on distributed systems, databases, and operating systems, and understand the common latency-causing issues in each situation.

In "Latency" you’ll learn how to:

•Define latency, distinguish it from bandwidth, and understand its impact on user experience

•Model performance with Little’s Law and Amdahl’s Law, then measure and visualize delays

•Optimize data access with colocation, replication, partitioning, and caching

•Accelerate logic with algorithmic improvements, memory tuning, and lock-free concurrency

•Minimize delays with asynchronous processing, predictive techniques, and speculative execution

Put simply, latency is the delay between a cause and effect. In practice, too much latency can create problems throughout a software system, ranging from inaccurate calculations and timeouts to impatient users simply abandoning your applications.

About the book:

"Latency: Reduce delay in software systems" shows you how to troubleshoot latency in existing applications and create low latency systems from the ground up. In it, you’ll discover high-impact fixes for measuring latency and advanced optimizations in memory management, concurrency models, and predictive execution.

About the listener: For software engineers with a working knowledge of backends. Examples in Rust.
