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
- Gzip Components
- Put Stylesheets at the Top
- Put Scripts at the Bottom
- Avoid CSS Expressions
- Reduce DNS Lookups
- 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.
"If everyone would implement just 20% of Steve's guidelines, the Web would be adramatically better place. Between this book and Steve's YSlow extension, there's reallyno 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
