If your browser already has a cached version of the library for some other site, it won't load it again. 如果您的浏览器已经为某个其他站点提供了库的缓存版本，则不会再次加载它。
Your browser may connect to Google or other CDN servers simultaneously, which may not happen if you are loading from your server. 您的浏览器可能会同时连接到Google或其他CDN服务器，如果从服务器加载，可能不会发生这种情况。
The latency in getting the file from a Google server is almost always significantly shorter than with your server. 从Google服务器获取文件的延迟几乎总是比服务器短得多。

The scenario where you may want to host on your site is if you are serving content for countries where Google, Google's CDN or similar are blocked. 您可能希望在自己的网站上托管的方案是，如果您要为Google，Google的CDN或类似网站被阻止的国家/地区提供内容。
