想到这个的一个原因是今天在网教拖 mirrors 的 debian liveCD,插网线开网络通出口1下载速度竟然只有约 250kB/s,顿时觉得不科学。

直接开 LUG VPN 继续下,速度没下过4MB/s。这是为何,求解答

你是从 mirrors.ustc.edu.cn 下载吗?在网络通出口1的情况下,traceroute mirrors.ustc.edu.cn 和 traceroute -6 mirrors.ustc.edu.cn 贴出结果看看?

刚才又试了试,速度没问题了。不过现在大中午的人比较少。

$ traceroute mirrors.ustc.edu.cn
traceroute to mirrors.ustc.edu.cn (202.38.95.110), 64 hops max
  1   210.45.73.254  0.344ms  0.307ms  0.367ms
  2   202.38.96.188  0.413ms  0.427ms  0.862ms
  3   202.38.95.110  0.545ms  0.519ms  0.312ms
$ traceroute6 mirrors.ustc.edu.cn
traceroute to mirrors.ustc.edu.cn (2001:da8:d800:95::110) from 2001:da8:d800:73:74f9:942e:6f39:a0b0, 30 hops max, 24 byte packets
 1  2001:da8:d800:73::1 (2001:da8:d800:73::1)  0.36 ms  0.274 ms  0.394 ms
 2  2001:da8:d800:ffff::4 (2001:da8:d800:ffff::4)  0.867 ms  0.573 ms  0.626 ms
 3  2001:da8:d800:95::110 (2001:da8:d800:95::110)  0.357 ms  0.259 ms  0.396 ms

昨天也试了试 traceroute,和今天的结果貌似是一样的。
