《High Performance Web Sites》读后感(一)：一本精炼的小书
在我手上的是东南大学出版社出版的影印版，150页不到的一本小书，分成2章预备知识，14个rules，一章TOP10站点性能分析比较。各个章节相对独立，而且有交叉参考。非常适合在床上，马桶上，地铁里随时找个感兴趣的话题来阅读。作者号称是“Chief Performance Yahoo! at Yahoo!”，此书可以说是作者在实际工作中的经验总结。
关于Web Sites的性能优化，读者或多或少在日常工作中积累了一定的经验。比如优化Web服务器，优化数据库，做Cache，混淆Javaｓｃｒｉｐｔ等等。这本书侧重Web前端的优化，有些内容很熟悉，比如Rule 1，2，3，4，10，有些却让我很惊讶，比如Rule 6，还有一些一直都很混淆的概念，比如HTTP协议的一些Headers。作者都试图在这14条Rules里面用文字，图片和实验来解释清楚。最后一个章节是几个大站点的性能分析，里面使用的工具和实验方法值得借鉴。
《High Performance Web Sites》读后感(二)：High Performance Web Sites
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
《High Performance Web Sites》读后感(三)：以功能先行的名义发誓
随着WEB APPS的发展，简单的功能实现已经不能满足用户对于互联网的需求。
在功能实现的基础上，一堆堆对于性能，使用的舒适度，UI的要求也不断地浮现。甚至可能触发更深层次的功能需求。
这本书对于WEB 前端的代码及整套的优化提出了14条准则，有一些属于纯前端的，比如CSS尽量靠前，JS尽量靠后，尽量少用css expression及如何灵活使用css expression都对已经了解写简单CSS，JS的开发人员提出了更高的要求。
还有一些CDN网络，AJAX的CACHE则对以CSS，JS为主业的人员更严厉。
不能再满足于能实现，而要向更优的实现进军。
