That's just the nature of cheap switching.  If you look at a Wireshark 
(Ethereal) capture of the conversation between your two hosts, you'll see tons 
of re-transmissions and TCP Window adjustments as the hosts try to negotiate 
the link.  Try dumbing the hosts down to 10Mb/Half (or Full) and see if your 
problems go away.

I believe you can also pick up a Cisco 3560 8 port 10/100 switch for around 
$800-$900 that will handle the L3 activities that you need.

Hope this helps!

You can also get a low end Netscreen (or what ever it is called today) for a
few hundred dollars.

I have a 172.16.X.X and a 10.1.1.X separated with a Netscreen 25. Copying
large file is not an issue.

Why are you using the Linksys?

If you need to firewall off a group of users you need a real
enterprise-grade firewall, not cheap consumer crap. A PIX 506E in only a
couple hundred USD these days and will blow a Linksys out of the water
in terms of performance and reliability.

If you're using the Linksys as a basic router (no NAT, no firewall, etc)
you really really need to get an enterprise-grade L3 switch - HP 2900 or
HP 3400cl or Cisco 3550. Said switches have IP routing implemented in
the switch fabric ASICs.
