    之前在windows8下换各种防火墙, dns方案, 都不管用, 国外下载不见有多少快, 尤其是flickr图片秀.
    下载只有几十k/s, 还严重下降到零就不动了.
    今天没事在虚拟机试装了fedora和ubuntu两个系统, 并且装上chinadns和unbound.
    果然下载速度快跟上, 和几个月前一样, 维持几百k/s, 有时冲上1m/s.
    fedora和ubuntu里国外下载速度差不多, 无视墙的存在.

    希望有人能解释为什么window系统下国外下载速度严重下降.
  • Fedora
  • 国外
  • Ubuntu

    纯属个人猜测：是否是某种劫持导致的呢？因为TCP包中有操作系统的信息，比如只要检测到是Windows就对端口进行限速之类的。

    也许吧, 之前我以为国际出口带宽出了大问题, 各种抽风

    强烈建议你把windows8格了，重装个fedora或ubuntu!。各种优越感，各种高大上！

    ubuntu 自带DNS缓存, TCP/UDP的 实现也不一样.

    @vimpreal 电信的国际出口带宽是肯定被限制了，你不用怀疑，这是我用了5年的vpn服务商给我的回复，至于你说的linux，我在android上面访问国外正常网站有的时候也蛮快的，也许他们真的控制精细点吧
