I have two computers. The both connect to a gigabit switch. The switch is connected to a router which runs at 100mb/s. The router is also the DHCP server in my home network. After the computers boot up, they first talk with the router to get IP etc. So they auto-negotiate at 100MB/s speed.



$ sudo ethtool eth0
[sudo] password for tao:
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Advertised pause frame use: No
Advertised auto-negotiation: Yes
Link partner advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Link partner advertised pause frame use: No
Link partner advertised auto-negotiation: Yes

Now, is there a way to make the two computers to transmit data between themselves at gigabit speed? My test shows they top out at 93mbps.
