网站打开慢常见情况解析

1，首先使用ping命令测试域名的联通性，是否延迟变大，或者丢包严重例如ping www.baidu.com

2.测试是否能够远程到服务器上，如果可以远程，打开任务管理器，查看网络使用率

一般情况，网上是100M或者1000M网卡，带宽是10M , 物理网卡是100M，利用到达或者超过10% 就是带宽跑满或者超过带宽，肯定会造成网站打开慢，在进程选项中，查看cpu或者内存使用比较高的，结束掉，观察带宽利用率是否降下来，如果是，进一步检查结束掉的进程对应的软件程序，如果不是，继续结束下一个较高进程

3.DNS解析有问题，也可能造成网站打开缓慢，这种情况，可以考虑更换网络配置信息处的DNS选项

4.数据库例如mysql 调用频繁，占用cpu过高，导致网站反应过慢，可以检查数据库配置，是否有bug漏洞，造成频繁查询调用，进行优化处理

5.某个jss文件或者图片加载时间过长，或者加载失败造成网页整体打开慢，用浏览器打开网站域名，同时按F12 点击network ，进行查看

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
