15% of maximum, is that all Gigabit offers?

Hi,
I have two Belkin Gigabit NICs and a Belkin gigabit switch, I found
that when I try to transfer 4-6GB files between them, I get an absolute
maximum of 15% of the 1gb bandwidth (150Mbps).

I'm using high quality CAT6 cables, running alone on the switch, I've
used a different Netgear gigabit switch, I've disabled the firewalls
and virus guards, stopped any unnecessary programs from running, I've
set both PCs up to have more resources for file sharing, I've run a
network tweak tool to adjust the registry for 10Mbps or higher, I've
tried pushing from one and pulling from the other, and still no
difference.

I've 'tweaked' both the NICs drivers settings (duplex, frame size etc.
to max) so that they're running as fast as they can, which has improved
the overall reliability (I can actually transfer the files now without
it saying the network is no longer available after threee minutes), but
it's still maxing out at 150Mbps.

One PC is running XP Home and has an AMD 3000 with 1GB RAM, the other
is a 1Ghz AMD with 768MB RAM on XP Media Centre. I've heard that the
computer can cause the network to slow, could this be the case here or
am I clutching at strawers?

If I try to transfer from either gigabit machine to any 100MB machine,
it runs at 100Mbps, no trouble at all.

Any advise on this (reg tweaks etc.) would be greatfully received.
 
Did you ever consider that your network is faster than your hard drives?
Always look at the links in the chain and don't get hung up on one link.
