Google在四月九号正式宣布了网站速度会影响搜索排名. 尽管权重不到1%, 但程序员在设计实现网站时就应该考虑更多的因素. 我在实现这个博客网站时就选择了要尽快显示内容, 为此省略了很多功能, 为的是要在2秒之内让访客看到内容.

下面提供的工具中前三个是Google官方博客里提到的. 前两个现在对Firefox和Chrome都提供了支持.

• Page Speed, evaluates the performance of web pages and gives suggestions for improvement. including Firefox, Chrome and Online version.
• YSlow, a free tool from Yahoo! that suggests ways to improve website speed,
• WebPagetest shows a waterfall view of your pages’ load performance plus an optimization checklist.
• Pingdom Tools: Every test also shows general statistics about the loaded page such as the total number of objects, total load time, and size including all objects.
• Webpage Analyzer: Their script calculates the size of individual elements and sums up each type of web page component

五月四号, Google 在Google Analytics加入测量报告. 不过这个选项的缺省值是关闭的. 要按照Google 的说明来设置.
