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.

"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,
