天生我才必有用

网站性能应该是仅次于网站功能的一个重要参考指标。有时功能做了非常不错的网站，最终去因为性能不佳而丧失了用户。应此Yahoo推出了Yslow来进行对您网站性能进行评测，YSlow也基本成为了完整性能的风向标。

WordPress是一个非常不错的建站工具，关于YSlow的解决方法就是：W3 Total Cache。

你可以通过安装W3 Total Cache 这个插件(http://wordpress.org/extend/plugins/w3-total-cache/)获得WordPress的性能最佳化。

Benefits:

• At least 10x improvement in overall site performance (Grade A in YSlow or significant Google Page Speed improvements) when fully configured
• Improve conversion rates and “site performance” which affect your site’s rank on Google.com
• “Instant” second page views (browser caching after first page view)
• Optimized progressive render (pages start rendering immediately)
• Reduced page load time: increased visitor time on site (visitors view more pages)
• Improved web server performance (sustain high traffic periods)
• Up to 80% bandwidth savings via minify and HTTP compression of HTML, CSS, JavaScript and feeds

YSlow是由Yahoo公司开发一个Firefox的插件，它和著名的FireBug插件集成在一起，对网页的性能(Performance)进行评估。可在Yahoo官方网站进行安装：https://addons.mozilla.org/en-US/firefox/addon/5369

包含了一下的功能：

• Performance report card
• HTTP/HTML summary
