As this is a dedicated server in a colo hundreds of km away, I have no means to check this easily. Especially I cannot change the setting from auto-neg. Btw, linux will show a negotiated 100/full link via mii-tool. > > # ifconfig re0 > > re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 > > options=88<VLAN_MTU,VLAN_HWCSUM> > > ether 00:21:85:63:74:34 > > inet6 fe80::221:85ff:fe63:7434%re0 prefixlen 64 scopeid 0x1 > > inet 46.4.12.147 netmask 0xffffffc0 broadcast 46.4.12.191 > > nd6 options=3<PERFORMNUD,ACCEPT_RTADV> > > media: Ethernet 100baseTX <full-duplex> (100baseTX <half-duplex>) > > status: active > > > > This time, it seems you used forced media configuration > instead of auto.

Sadly, none of these options are available to me :/ But even 100/half should give more than enough performance, right?
