Steve Souders, "High Performance Web Sites: Essential Knowledge for Front-End Engineers"
O'Reilly Media, Inc. (September 11, 2007) | ISBN: 0596529309 | 168 pages | PDF | 2 Mb
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.
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
Put Stylesheets at the Top
Put Scripts at the Bottom
Avoid CSS Expressions
Reduce DNS Lookups
Remove Duplicates Scripts
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.
"If everyone would implement just 20% of Steve's guidelines, the Web would be a dramatically better place. Between this book and Steve's YSlow extension, there's really no excuse for having a sluggish web site anymore."
-Joe Hewitt, Developer of Firebug debugger and Mozilla's DOM Inspector
"Steve Souders has done a fantastic job of distilling a massive, semi-arcane art down to a set of concise, actionable, pragmatic engineering steps that will change the world of web performance."
-Eric Lawrence, Developer of the Fiddler Web Debugger, Microsoft Corporation
