CDN 不再引入,我测试了一下使用引入 CDN 和不使用,不使用会比使用时间少。网上不少文章测试 CDN 速度块,这个开发者可 以实际测试一下。</p><p>另外项目中使用的是公共 CDN 不稳定,域名解析也是需要时间的(如果你要使用请尽量使用同一个域名)</p><p>因为页面每次遇到<code>&lt;script&gt;</code>标签都会停下来解析执行,所以应该尽可能减少<code>&lt;script&gt;</code>标签的数量 <code>HTTP</code>请求存在一定的开销100K 的文件比 5 个 20K 的文件下载的更快,所以较少脚本数量也是很有必要的</p><p>暂时还没有研究放到自己的 cdn 服务器上。</p><div class="language-javascript"><button title="Copy Code" class="copy"></button><span class="lang">javascript</span><pre class="shiki
