我们先来看看如何正确的测试一个机房的速度。

第一个办法也是最好的办法，PING值：

目标IP，或者域名都可以，举例 www.edong.com 61.152.105.35

开始菜单 －> 运行 －> 输入CMD －> 在DOS界面输入 “ping 222.191.251.180 -t” 或者 "ping www.edong.com -t "

注意如果没有 －t 那么ping值只有4个不具备代表性，－t参数就是让ping一直接续下去，知道你 手工 ctrl C 停止。

上海电信ADSL ping的结果：

C:\Documents and Settings\Administrator>ping www.edong.com -t 【输入的命令】
