slow data movement accross lan

[Harry Putnam]

Wondering if I've run into something yarrow specific here.

I'm noticing what seem like very slow speeds moving data from a
running rh 9 box to a yarrow box accross a local network.  With ncftp
running from yarrow to rh9 on a get action I'm seeing a high of 5.65
KBs (mostly less) being moved.  Isn't that very slow?  

I have nsf setup between the two as well but a cp -a seems slow too.
Its way faster than ftp of course but still a timed cp -a of some
380868986k across nfs directory looks like:
(over 1/2 hour for some 380+MB)
real    32m40.217s
user    0m0.060s
sys     0m1.490s

(That seems quite slow too isn't it?)
So maybe there is more than ethernet speed involved?

Concerning the ethernet speed:
I've sort of lost track of how to check on my ethernet settings.
Seems like we once used something like mii-tool.

That returns:
 # mii-tool
eth0: 10 Mbit, full duplex, link ok

And dmesg shows the device on yarrow:
