If you set it to full-duplex and it comes in in full-duplex make
sure to watch for collisions and errors on the interface to
determine whether you should leave it that way.


This looks like one of those "I thought I knew what I wanted to do
here" jobs. 'man mii-tool' and some second thoughts seem to be in
order.

Many thanks.
Full-duplex is great... as long as the equipment can handle it and
your increase in throughput isn't made up entirely of mangled
packets.
Just done a mii-tool NICs status check. Everything is running at full
speed and full duplex already. Not much I can do to improve that I'd
think. Kind of an anticlimax as I'd hoped something might be fixable
to squeeze a bit more performance through the wires. Ah well.

Thanks for the pointers. :)

Yep... hard to get a better connection than that.

i'm replying to you because i'm eagered to here your opinion

if your goal is mainly to increase throughput of large files than jumbo
frames can be used, although i haven't tested this myself and it's
mainly hearsay to me

If the MTU (Maximum Transmission Unit) on the far end is set to the
default (1500 unix, 1300 something under windows) it doesn't matter what
you set your frames to. Your packets are still going to get chopped up to
the largest negotiated size.
