Well from experience here i know that the 10/100/1000 mbit adapter from
marvell works well in my networks setup. I'm running 7 machines connected to
a 8 port 10/100/1000 switch, the last port is connected to my cable modem
which is 10/100mbits. recently i upgraded to winxp pro 64bit and noticed
that my network connection was a little slow using the drivers that were
defaultly installed for my machine. after a run with windows update i
downloaded the updated drivers for my card and everything is back to normal.
out of curiosity i tried downloaded the beta drivers from marvell/yukon and
i seen another small imporvement in my transfer speeds.
I'd definately suggest checking your drivers and trying them from both
places, but marvell also supplies a small program to test your cable. You
might find that you cable is slightly unplugged and not getting the best
connection. which would cause slow speeds due to failed packets which need
to be retransmitted.
now the firewire drive should be pretty quick, I believe most are still
rated at 400mbits which would be about 4 times faster than the ethernet
network you are running.
I'd also look at the anti virus solutions you are running on the machines,
some antivirus programs take alot of time to scan the files that you are
sending. i'm running Nod32 64bit edition right now and it is very quick.
there are a few other things to try but let us know what happens from here.
