网站打开慢原因排查

检查域名解析是否正确

域名需要全部做别名解析到s-xxxxx.abc188.com,特别是:智能多线/西部数码双线机房、

主机线路是否一致

检查一下您购买的是否是单线（中国电信）或者港台机房，如果是单线的主机跨网访问会比较慢，如果是港台

主机建议尽快备案后升级回国内机房

检查服务器资源使用是否正常

登陆我司后台-业务管理-独立Ip主机管理-管理-性能视图

此处核查您主机的带宽，CPU，磁盘读写是否正常，如果有异常，请远程登录服务器检查一下原因

带宽下载速度之间单位换算

带宽和下载速度都是网络传输速度的单位，它们之间的换算关系如下： 1 Mbps（兆比特/秒）= 1024 Kbps（千比特/秒） 1 Mbps = 0.125 MB/s（兆字节/秒） 1 GB（千兆字节）= 1024 MB（兆字节）因此，如果您的带宽为20 Mbps，则您最大的下载速度为： 20 Mbps × 0.125 = 2.5 MB/s 或者，如果您的下载速度为5 MB/s，则您

网站流量超标排查

网站出现流量超标时分析及解决思路为：查看网站访问统计---->结合访问统计分析网站访问日志---->确定原因采取相应措施。一．查看网站访问统计1. 登录到虚拟主机管理面板，点击“访问统计”图片.png2.首先查看访问统计中浏览器与非浏览器流量确定流量类型。图片.png3.根据流量类型详细查看访问统计数据：3.1如是浏览器流量占用高，可查看图片.png图片.png图片.png图片.png

令网站打开提高速度的7大秘方

1. 优化图片：使用适当的格式和尺寸来实现快速加载图片。 2. 压缩文件：压缩文件大小以减少加载时间。 3. 简化代码：消除不必要的代码，使页面更轻量级，加载更快。 4. 将CSS和JS文件放在顶部：这会在页面加载时优先加载CSS和JS，并且减少延迟。 5. 使用CDN：CDN（内容分发网络）通过运用多个位于全球各地的服务器来缓存和分发网站内容。这可以显著加快网站的加载时间。 6. 使缓

WEB站点性能优化实践（加载速度提升2s）

感谢大CC的投稿：进行优化前，关键是剖析当前的web性能，找到性能瓶颈，从而确定最需改进的地方;如果精力有限，首先将精力放在能明显提升性能的改进点上;《高性能网站建设指南》提出了一个性能黄金法则：只有10%-20%的最终用户响应时间花在了下载HTML文档上;其余的80%-90%的时间花在了下载页面中的所有组件上。由于本文将实施一个完整的优化流程，所以，我们还是从后台开始;案例说明：优化之前的网站规
