Linux系统下可以通过下面命令核查网卡带宽：

[root@www ]#ethtool eth0
Settings for eth0:
        Supported ports: [ TP ]
        Supported link modes:  10baseT/Half 10baseT/Full
                               100baseT/Half 100baseT/Full
                               1000baseT/Full

                               1000baseT/Full
        Advertised auto-negotiation: Yes
        //其它的信息不用管它，下面Speed这一行就是网卡目前的带宽
        Speed:1000Mb/s
        Duplex: Full
