As a datapoint - I usually get about 6MB/S on a 100M switched full
duplex lan,  and the machines involved don't have to be anything
special...  any PII can do that.

Note I'm fairly sure that scp reports in Mega Bytes per second, and a
LAN is usually rated in Mega Bits per second - so an scp that reports
6 MB/s would represent at least 6x8=72 mega bits per second.  Add
overhead for the protocols etc and there's your 100Meg LAN speed.

Are you using a hub rather than a switch?  I wonder if you are running
in half duplex and thus your 3meg speed might be all it can do...

assuming you are using an ethernet card labelled eth0, what does

sudo /sbin/mii-tool -v eth0

show?
