在运行框里输入perfmon.exe，然后打开资源监视器会看到实时的网速 在开始-->运行-->输入cmd 然后再命令行下面输入比如我们这个DNS是 ping 202.103.44.150 -t 或者ping网关都可以的。 如： C:Documents and SettingsAdministrator>ping 202.101.224.68 -l 1000 Pinging 202.101.224.68 with 1000 bytes of data: Reply from 202.101.224.68: bytes=1000 time=38ms TTL=251 Reply from 202.101.224.68: bytes=1000 time=38ms TTL=251 Reply from 202.101.224.68: bytes=1000 time=38ms TTL=251 Reply from 202.101.224.68: bytes=1000 time=38ms TTL=251 Ping statistics for 202.101.224.68: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 38ms, Maximum = 38ms, Average = 38ms 根据上述发送及返回的信息可以简单得出到地址202.101.224.68的网速为： 网速等于≈(发送的字节数/返回的时间[毫秒])K字节 ≈1000/38K字节 ≈26.32K字节
