从去年开始,浏览海浩越来越慢,最近一段时间,就别提了,难以忍受
开始也没大在意,以为各个会议影响,过一段时间就好了
前几天注意了一下,原来是丢包,这是我机器上的状况
netstat -s -p tcp
TCP Statistics for IPv4
Active Opens = 13099
Passive Opens = 11774
Failed Connection Attempts = 63
Reset Connections = 314
Current Connections = 7
Segments Received = 242556
Segments Sent = 222780
Segments Retransmitted = 981
还凑合,重新传输的只占很少一部分
可是
ping -t bbs.highot.net
Ping statistics for 218.31.79.200:
Packets: Sent = 121, Received = 88, Lost = 33 (27% loss),
Approximate round trip times in milli-seconds:
Minimum = 169ms, Maximum = 199ms, Average = 177ms
round trip times 只有200ms,可丢包率却有27%
ping -t www.imagegarden.net
Ping statistics for 202.101.42.96:
Packets: Sent = 71, Received = 63, Lost = 8 (11% loss),
Approximate round trip times in milli-seconds:
Minimum = 368ms, Maximum = 512ms, Average = 414ms
丢包率也不低,虽说时间比海浩还要长,可速度还能忍受,
上面两个网站是俺常去的
从我机器上traceroute,所有的节点全都直接扔包,nnd,安全防范搞得不错
用visualroute http://www.linkwan.com/vr2/#world
从上海trace,有个狗屎路由器丢包率100%
北京,无丢包
香港,10%
德国,无丢包
台北,100%
日本,无丢包
原因分析
1.某个路由器质量不好----不大像
2.路由器超负荷
3.路由器错误配置
解决办法
1.找代理-----哭,不过速度快多了
2.等升级-----遥遥无期
结论
真tmd倒霉
另外俺想下载visualroute软件,http://www.visualroute.com/ |
