如何确定网站的加载时间

Question

我正在为客户创建专业的网站，这是我的第一个项目，并且我使用了太多的库，例如Velocity.js，jquery，jquery.ui，animate.css，还有一些用于jquery的图像滑块插件，现在我正在使用min版本和所有文件都已下载到我的计算机中，但是当我将网站启用时，它将严重影响网站的加载时间，还是正常的。

You can put it up. Test it Click here . But the best way is to put it up and test the ping.

Answer 2

Yes, it will severely affect the loading of the page. Chrome comes with developer tools out of the box, and Firebug for Firefox is only a couple of clicks away. That, combined with the RTT time and badnwidth to the site gives you enough information to calculate exactly how slow the first hit page load time.

Assuming that caching is configured correctly, subsequent page transitions should be faster - but even loading all this javascript from cache and parsing it will have a big impact on the load time. Note that in the of Dokuwiki, the CMS already handles merging of javascript into a single file.

Using PJax or similar will help with subsequent transitions. Using online repositories for standard libraries does not help with performance. Minimizing the javascript does not give very big wins (since you are already compressing the files on the fly, aren't you?)

There's big wins to be had from defering Javascript loading and stripping/optimizing/merging CSS files.

There are a lot of other things you can do to make your page render faster - but space here is too limited.
