Product Description
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, Microsoft Corporation

5.0 out of 5 stars Fast Read -- Pass It Along, September 17, 2007

By	Brett Merkey (Palm Harbor, FL United States) - See all my reviews (REAL NAME)

§
_High Performance Web Sites_ is one of those books that will get read by more people than buy it because it is both a fast read and organized into clearly differentiated subjects. This makes it easy to pick up for a moment or pass along to team members with different specialties.

Each of these "14 Steps to Faster-Loading Web Sites" (listed in the editorial review above) is itself divided into related tips with practical pointers. The fact that the book is full of these pointers is not the only value I extracted. We also get something a bit more subtle. The fact that the author is a performance expert at one of the mega-companies that define the Web for most of us lends authority to the book. It is easy to have confidence that his practical experience will have immediate lessons for teams with the same problems, if on a smaller scale.

Steve Souders provides a special addition to his tips: his example pages offer direct comparisons and means to make our own tests. This is something rarely encountered in such books. The book ends with a 30-page chapter where he deconstructs 10 of the top Web sites in the U.S. using the rules and tools described in the book.

3.0 out of 5 stars I expected more..., January 10, 2008

By	NJP (Ohio) (Cincinnati) - See all my reviews

While the information in the book is good information to know, it is (as others have said) information that pretty much gave a "yeah, I knew that" type of impression. And at only 137 pages of text, it's a very light read. If you are a new web developer, this is a nice collection of tips. As an experienced developer, there's nothing new here. And at $29 for its minimal 137 pages, it's really just an expensive checklist of 14 simple items. Too pricey for what you get in my opinion.

2.0 out of 5 stars Good ideas, poor book, December 22, 2007

By	E. Welker (Maryland, USA) - See all my reviews (REAL NAME)

The ideas in the book are excellent. I'm all for an organized checklist of techniques to make web sites faster. The problem, is that once you have read the documentation for Yslow (the firebug plugin that grades sites based on these criteria) you will find the book provides little to no more substantive information. I had looked forward to it, purchased it, and have since given it away. I tried to give it the benefit of the doubt, as I love the ideas, but this book just didn't deliver.
