Slow LAN throughput

I have 2 computers sharing a cable modem line using a 4-port Linksys router and 2 Linksys NICs. Everything is working fine, except transferring files between computers seems slow. Both computers are linked at 100Mbs, but when I move a file from one computer to the other in Windows Explorer, NetStat Live tells me it's moving at about 18Mbs. That's 80Mbs left unused.
Does anyone have any suggestions?
 
One computer has Windows 2000 SP2 and the other has Windows NT 4.0 Workstation SP6a. Both are networking OS's so shouldn't things be more streamlined? I would expect this from Win98, but NT?
 
well, file sharing in windows just isn't that fast. Are your NICs set to autonegotiate speed/duplex?

and finally, you are limited by hard drive performance more than anything else.
 
Are the cables high quality CAT5e?

I don't know what the performance is of the Linksys cards myself. I have 3com nics in my systems and I can transfer a 700 meg file from one machine to the other in under 3 minutes. Hard drive speed could be another factor, but I would look at the cabling first.
 
For what it's worth: Moving files between my WinNT4 server and Win98SE workstation via 10/100Mbps NIC's, Cat5 cable and Netgear FS105 fast ethernet switch I max out at about 21.6Mbps.
