我必须下载 yslow 吗？
是否没有网页可以让我输入 URL 并获取 yslow 值之类的内容？ 看起来它应该比为我的浏览器下载插件更容易。我通常不使用 firebug / yslow 进行编程，我认为应该可以通过表单提交来执行像 yslow 这样的测试。 感谢您的回复
Is there no webpage where I just can input my URL and get something like yslow values?
It seems it should be easier than having to download the plugin for my browser. I usually don't program with firebug / yslow and I think it should be possible to perform a test like yslow by form submission.
Thanks for replying

任何此类服务都可能很快就会超载，受到广泛的滥用，而且利润不会过高。
重要的一点是，这样的服务将位于某个地方的高速数据中心，因此会产生相当无用的结果。您希望在典型的用户端点进行性能采样，并且需要在 Web 浏览器中进行。当您坐在浏览器面前时，为什么要将浏览器复制为 Web 服务呢？
注意 Google Analytics 和网站站长工具尝试执行某些网站性能指标。
Any such service is likely to be overloaded pretty quickly, subject to rampant abuse, and not overly profitable.
A major point is that such a service would be in a high speed data center somewhere and so produce pretty useless results. You want performance sampling at typical user endpoints, and it needs to be in a web browser. Why duplicate a browser as a web service when you are sitting in front of one.
Note Google Analytics and Webmaster Tools attempt to perform some website performance metrics.

http://tools.pingdom.com/ will give you some information on how long resources in the page take to load, and the page weight, but tools like YSlow and PageSpeed are a lot more informative.
If you do not want to install Firebug and plugins, abiding by as many of the YSlow Best Practices for Speeding Up Your Web Site as you can, will put you in good stead, prior to requiring any tools for fine tuning.
