网站打开慢常规问题排查

如果有遇见网站访问慢，建议首先从以下几个方法检测一下，是否是服务器配置或者网络的原因

1. 检查域名解析是否正确，我司虚拟主机默认推荐做别名解析到赠送的二级域名（xxxxx.gotoipx.com）

特别注意（西部双线、多线机房）此机房是通过CDN实现的双/多线，如果是做的A纪录会造成联通和其它线路打开慢

必须做别名解析到我司赠送的二级域名上面，顶级域名不能做别名的，可以解析到Ip后做一个301跳转到www域名上面

另:我司的域名支持顶级域名做别名解析

2. ping一下您的域名，看看延迟是否正常（开始-运行-CMD回车）

如果时间值大于100，则网络连接质量有异常，此时如果您购买的是单线主机，请核实您主机线路和您当前本地线路是

否一致，如果不一致，建议升级到多线或者双线主机，如果您当前已经是双线或者多线，请把此图提交到工单中，

方便我司技术检查处理

3. 如果非上述两个原因，则可能是服务器异常或者程序异常，具体请联系程序员或者提交工单，我司检查原因

如何选择合适的虚拟主机

1. 考虑使用场景：首先需要考虑选择虚拟主机的使用场景，例如是否是建立个人博客、搭建企业展示网站还是电子商务平台等等，每种场景对应着不同的主机要求和配置，因此在选择虚拟主机时，要根据自身的使用场景，合理挑选尺寸。 2. 考虑主机特性：当选择了自身的使用场景后，就应考虑虚拟主机的特性，比如cpu核心数、内存大小、内存类型、硬盘大小和类型等，根据使用负载的大小，合理选择满足自身需求的虚拟主机。

网站打开速度慢？影响网站打开速度的因素有哪些？

网站打开速度慢？一般来说影响网站打开速度的因素有5点，SEOer一定要记住：1.用户网络用户所在的网络是否顺畅、带宽是多少，都会影响网站打开的速度。就像用手机打电话，如果你所在的地方网络不畅通，电话就拨不出去。设备用户所使用的设备的运行速度也会影响网站打开速度。还是以打电话为例，如果手机反应慢，拨号速度也会慢。2. DNS配置DNS服务器本身的配置会影响DNS服务器的运行速度。自身环境DNS服务器

网站访问速度慢这个教程帮助你！

今天接到一个朋友的咨询，是做了一个小程序，平时也就一天几百个人访问使用，但卡顿比较明显。于是我们看了一下，确实比较卡。CPU、内存等各方面差看了一下。内存是没有问题的，占用20%左右。但，CPU占用比较多：服务器配置是很给力的，这种配置可以说是神级别了：因为不是自己做的程序，还是不敢贸然下结论。朋友给的线索是：以前刚用的时候没有感觉卡顿，就这些天才有的卡顿。于是有了几个猜测：一、服务器被攻击了有很
