High Performance Web Sites: Essential Knowledge for Front-End Engineers

Writer: Steve
Published: 11 November 2007

Want your web site to display more quickly? This book presents 14 specific rules that will cut 25% to 50% off response time when users request a page. Author Steve Souders, in his job as Chief Performance Yahoo!, collected these best practices while optimizing some of the most-visited pages on the Web. Even sites that had already been highly optimized, such as Yahoo! Search and the Yahoo! Front Page, were able to benefit from these surprisingly simple performance guidelines.

The rules in High Performance Web Sites explain how you can optimize the performance of the Ajax, CSS, JavaScript, Flash, and images that you've already built into your site -- adjustments that are critical for any rich web application. Other sources of information pay a lot of attention to tuning web servers, databases, and hardware, but the bulk of display time is taken up on the browser side and by the communication between server and browser. High Performance Web Sites covers every aspect of that process.

Each performance rule is supported by specific examples, and code snippets are available on the book's companion web site. The rules include how to:

Make Fewer HTTP Requests

Use a Content Delivery Network

Add an Expires Header

Gzip Components

Put Stylesheets at the Top

Put Scripts at the Bottom

Avoid CSS Expressions

Make JavaScript and CSS External

Reduce DNS Lookups

Minify JavaScript

Avoid Redirects

Remove Duplicates Scripts

Configure ETags

Make Ajax Cacheable

If you're building pages for high traffic destinations and want to optimize the experience of users visiting your site, this book is indispensable.
