大家好，这个本人的第一贴，有个问题想问大家，也不知道发的地方对不对。
网络环境：
6人共享2M带宽，4口路由器拖3台PC+1交换机（+3台PC）
不知道上面的结构大家看懂了没有。

问题是当LAN内有人用迅雷DOWNLOAD的时候，ping 路由器就会非常慢。
可是按道理来说，开迅雷的时候应该是ping外网慢，而ping内网正常啊！
希望各位高手给分析一下。
下面是ping的数据，上半部分是其他PC开迅雷DOWN的时候的数据，下半部分是迅雷关闭后的数据。

路由器性能太差,换一个好点的~

但是以前没有这种情况出现啊。
是最近才有的。
请问还可能有其他的原因吗？

那是路由器老化了,还是建意先换一个试试~~

才用了半年的。
我看也只有换新的看看了。
郁闷ing
另外谢谢老大了。

迅雷下载有以下特点,并发连接数多,下载的同时要上传.
所以1.对路由器的性能要求高:路由器要做转发,还要做NAT所以性能不好的路由器响应时间会加大或丢包.
      2.你们可能是使HUB,所以共享式构中当数据流量过大时,也会出现掉包!

换个性能好点的路由器,使用迅雷的话会占用所有的线程数,如果设备性能差,带宽少的话,容易造成网络掉包情况!!

是网络出口的问题吧，看看交换机和路由器的端口模式是否匹配，还有路由器的CPU利用率为多少。一般掉包都是端口模式不匹配或CPU利用率过高引起的！
