You only distinctly mentioned two machines - are they by chance connected
via a nulled ethernet cable? If not, what quality of hub/switch are they
connected to?
Your 700-800kbps seems a little slow in the first place for 10Mb ethernet,
even using some of the cheapest cards on the market. I use primarily the
Netgear FA310TX and Intel fxp cards, and get much higher rates, even at
10Mb -- 100Mb obviously goes a whole lot faster.
This kind of problem is often caused by the auto-negotiation of speed &
duplex settings between the card & the "other end" - hub, switch, another
card, whatever. I've run into problems where the auto-neg results in
<1Kb/sec transfer rates - manually specifying the parameters fixed these
machines. A little more about your network setup and some sections of
your dmesg output would be helpful.
