As long as there's been a Web, people have been trying to make it faster. The maturation of the Web has meant more users, more data, more features, and consequently longer waits on the Web. Improved performance has become a critical factor in determining the usability of the Web in general and of individual sites in particular.Web Performance Tuning, 2nd Edition is about getting the best possible performance from the Web. This book isn't just about tuning web server software; it's also about streamlining web content, getting optimal performance from a browser, tuning both client and server hardware, and maximizing the capacity of the network itself.Web Performance Tuning hits the ground running, giving concrete advice for quick results -- the "blunt instruments" for improving crippled performance right away. The book then shifts gears to give a conceptual background of the principles of computing performance. The latter half of the book examines each element of a web transaction -- from client to network to server -- to find the weak links in the chain and show how to strengthen them.In this second edition, the book has been significantly expanded to include: New chapters on Web site architecture, security, reliability, and their impact on performance Detailed discussion of scalability of Java on multi-processor servers Perl scripts for writing web performance spiders that handle logins, cookies, SSL, and more Detailed instructions on how to use Perl DBI and the open source program gnuplot to generate performance graphs on the fly Coverage of rstat, a Unix-based open source utility for gathering performance statistics remotely In addition, the book includes many more examples and graphs of real-world performance problems and their solutions, and has been updated for Java 2.This book is for anyone who has waited too long for a web page to display, or watched the servers they manage slow to a crawl. It's about making the Web more usable for everyone.

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 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
