On today’s web, performance isn’t just a nice-to-have—it’s essential. A slow or unstable experience drives users away, while a fast, reliable one builds trust and keeps them engaged. Web Performance Engineering is a comprehensive, hands-on guide for developers, technical leads, and performance engineers focused on delivering high-impact, user-first web experiences. Written by Addy Osmani, an engineering leader on the Google Chrome team, this book combines deep technical insight with a strong emphasis on usability and real-world effectiveness.

Through case studies, modern optimization techniques, and a user-centered approach, you’ll learn how to identify bottlenecks, debug performance issues, and apply improvements that make a measurable difference. Grounded in current browser internals and performance metrics, this book prepares you to design and maintain faster, more resilient websites at scale.

Understand how users perceive speed—and why it matters
Evaluate and improve performance using key metrics
Optimize for stability, responsiveness, and load time
Identify and address the most common performance bottlenecks
Apply real-world strategies that lead to lasting results
