list-style: none; margin: 0px; scrollbar-width: none; font-weight: 600;">压缩图片</span><p>：使用专业的图片压缩工具，如TinyPNG、ImageOptim等，在不影响图片视觉效果的前提下，大幅减小图片文件大小。例如，一张原本大小为2MB的高清图片，经过压缩后可能只有几百KB，能显著加快页面加载速度。</p></li><li><span style="box-sizing: border-box; padding: 0px; -webkit-font-smoothing: antialiased; font-family: -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Ubuntu, &quot;Helvetica Neue&quot;, Helvetica, Arial, &quot;PingFang SC&quot;, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei UI&quot;, &quot;Microsoft YaHei&quot;, &quot;Source Han Sans CN&quot;, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;; list-style: none; margin: 0px; scrollbar-width: none; font-weight: 600;">选择合适的图片格式</span><p>：根据图片类型选择合适的格式，如JPEG适合色彩丰富的照片，PNG适合透明背景或需要高质量的图形，WebP格式则能在保证质量的同时提供更小的文件体积。</p></li><li><span style="box-sizing: border-box; padding: 0px; -webkit-font-smoothing: antialiased; font-family: -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Ubuntu, &quot;Helvetica Neue&quot;, Helvetica, Arial, &quot;PingFang SC&quot;, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei UI&quot;, &quot;Microsoft YaHei&quot;, &quot;Source Han Sans CN&quot;, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;; list-style: none; margin: 0px; scrollbar-width: none; font-weight: 600;">使用图片懒加载</span><p>：当用户滚动页面时，才加载可视区域内的图片，避免一次性加载所有图片导致页面加载缓慢。例如，在一些电商网站中，商品列表页的图片使用懒加载技术，用户初始打开页面时只加载首屏的图片，向下滚动时再加载后续图片。</p></li></ul><li><span style="box-sizing: border-box;

list-style: none; margin: 0px; scrollbar-width: none; font-weight: 600;">减少HTTP请求</span><p>：合并CSS、JavaScript文件，使用CSS Sprites技术合并小图标，减少浏览器向服务器发送的请求次数。例如，将多个CSS文件合并为一个文件，将多个小图标合并成一张大图，通过CSS定位显示不同的图标。</p></li><li><span style="box-sizing: border-box; padding: 0px; -webkit-font-smoothing: antialiased; font-family: -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Ubuntu, &quot;Helvetica Neue&quot;, Helvetica, Arial, &quot;PingFang SC&quot;, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei UI&quot;, &quot;Microsoft YaHei&quot;, &quot;Source Han Sans CN&quot;, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;; list-style: none; margin: 0px; scrollbar-width: none; font-weight: 600;">压缩代码</span><p>：对HTML、CSS、JavaScript代码进行压缩，去除不必要的空格、注释、换行符等，减小文件体积。可以使用工具如UglifyJS（用于JavaScript）、CSSNano（用于CSS）等。</p></li><li><span style="box-sizing: border-box; padding: 0px; -webkit-font-smoothing: antialiased; font-family: -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Ubuntu, &quot;Helvetica Neue&quot;, Helvetica, Arial, &quot;PingFang SC&quot;, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei UI&quot;, &quot;Microsoft YaHei&quot;, &quot;Source Han Sans CN&quot;, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;; list-style: none; margin: 0px; scrollbar-width: none; font-weight: 600;">优化CSS和JavaScript的加载方式</span><p>：将CSS文件放在HTML的<code class=" inline" style="box-sizing: border-box; padding: 1px 4px; -webkit-font-smoothing: antialiased; font-family: SFMono-Regular, Consolas, &quot;Liberation Mono&quot;, Menlo, Courier, monospace; list-style: none; margin: 0px 2px; scrollbar-width: none; font-size: 12.75px; tab-size: 4; background-color: rgba(27, 31, 35, 0.05); border-radius: 3px;">&lt;head&gt;</code>标签中，确保页面样式能尽快加载；将JavaScript文件放在HTML的底部（<code class=" inline" style="box-sizing: border-box; padding: 1px 4px; -webkit-font-smoothing: antialiased; font-family: SFMono-Regular, Consolas, &quot;Liberation Mono&quot;, Menlo, Courier, monospace;

padding: 1px 4px; -webkit-font-smoothing: antialiased; font-family: SFMono-Regular, Consolas, &quot;Liberation Mono&quot;, Menlo, Courier, monospace; list-style: none; margin: 0px 2px; scrollbar-width: none; font-size: 12.75px; tab-size: 4; background-color: rgba(27, 31, 35, 0.05); border-radius: 3px;">async</code>或<code class=" inline" style="box-sizing: border-box; padding: 1px 4px; -webkit-font-smoothing: antialiased; font-family: SFMono-Regular, Consolas, &quot;Liberation Mono&quot;, Menlo, Courier, monospace; list-style: none; margin: 0px 2px; scrollbar-width: none; font-size: 12.75px; tab-size: 4; background-color: rgba(27, 31, 35, 0.05);

list-style: none; margin: 0px; scrollbar-width: none; font-weight: 600;">浏览器缓存</span><p>：通过设置HTTP缓存头（如<code class=" inline" style="box-sizing: border-box; padding: 1px 4px; -webkit-font-smoothing: antialiased; font-family: SFMono-Regular, Consolas, &quot;Liberation Mono&quot;, Menlo, Courier, monospace; list-style: none; margin: 0px 2px; scrollbar-width: none; font-size: 12.75px; tab-size: 4; background-color: rgba(27, 31, 35, 0.05); border-radius: 3px;">Cache-Control</code>、<code class=" inline" style="box-sizing: border-box; padding: 1px 4px; -webkit-font-smoothing: antialiased; font-family: SFMono-Regular, Consolas, &quot;Liberation Mono&quot;, Menlo, Courier, monospace;

padding: 0px; -webkit-font-smoothing: antialiased; font-family: -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Ubuntu, &quot;Helvetica Neue&quot;, Helvetica, Arial, &quot;PingFang SC&quot;, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei UI&quot;, &quot;Microsoft YaHei&quot;, &quot;Source Han Sans CN&quot;, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;; list-style: none; margin: 0px; scrollbar-width: none; font-weight: 600;">CDN缓存</span><p>：利用内容分发网络（CDN）将网站的静态资源缓存到全球各地的节点服务器上，用户访问网站时，从距离最近的节点服务器获取资源，提高资源加载速度。例如，一家面向全球用户的网站使用CDN服务，不同地区的用户访问网站时，都能快速加载资源，提升访问体验。</p></li></ul></ul><h4 style="box-sizing: border-box;

list-style: none; margin: 0px; scrollbar-width: none; font-weight: 600;">优化算法和数据结构</span><p>：在后端代码中，选择合适的算法和数据结构能显著提高程序的执行效率。例如，在处理大量数据排序时，使用快速排序算法比冒泡排序算法效率更高。</p></li><li><span style="box-sizing: border-box; padding: 0px; -webkit-font-smoothing: antialiased; font-family: -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Ubuntu, &quot;Helvetica Neue&quot;, Helvetica, Arial, &quot;PingFang SC&quot;, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei UI&quot;, &quot;Microsoft YaHei&quot;, &quot;Source Han Sans CN&quot;, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;; list-style: none; margin: 0px; scrollbar-width: none; font-weight: 600;">减少数据库查询次数</span><p>：避免在循环中频繁查询数据库，可以通过使用缓存、批量查询、连接查询等方式减少数据库访问。例如，在显示用户订单列表时，一次性查询出订单及其关联的商品信息，而不是分别查询订单和商品。</p></li><li><span style="box-sizing: border-box; padding: 0px; -webkit-font-smoothing: antialiased; font-family: -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Ubuntu, &quot;Helvetica Neue&quot;, Helvetica, Arial, &quot;PingFang SC&quot;, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei UI&quot;, &quot;Microsoft YaHei&quot;, &quot;Source Han Sans CN&quot;, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;;
