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

服务器1M带宽同时能承受多少人在线

导读：很多站长在选购主机时会面对一个问题，带宽1M到底能容纳多少人呢?而站长Wings Wu给出了一个参考答案，供大家参考。另外，在买主机时一定要了解“共享宽带”和“独享宽带”。“共享100M“远不及“独享10M”的速度快。最近网站的流量一直在增长，这个肯定是好事。不过也有个麻烦的问题，目前本站用的的虚拟空间，每月流量30G，虽然95%的图片都已外链，但流量还是很吃紧，日均2000ip，4月份流量
