看看我这time和掉包率,这是上午网速快的时候PING 的.
现在打开网页嗷嗷的,超级爽,
所以,网速并不是完全看ping 值的.

也有可能是网通电信接口问题,你的服务商和上面这个IP地址是电信,我是网通,可能造成大批丢包.

那要怎么检测？？

我也有类似这种情况的，不过基本上是早上上班的时候，这个时候是正常的！

上面这个是单机测试的！！或者说是正常的时候的情况！！！

但是我这里PING 值一高。网速就超卡！！还会出现掉线才麻烦撒！！要是掉包不影响网速我也就不甩他了！！！

我晕，这个只能说明你和这个接点的连通性，多找几个IP试下，对方主机自身问题也有可能。PING只是一个连通性测试，包侦探
