Thanks for your suggested. I've defeated rss. Here are the results:
Straight line to router: 20 Kbs down
Gig switch in middle 300 Kbs
Cheap hub in middle: 2200 Kbs
I've pulled all optimization from the onboard Intell Pro Ethernet chip, set
static IP, turned off Network discovery, disabled autotuning, upgraded all
drivers and patches, and all the other things that 2 weeks of searching has
turned up. Performance under Vista is lousy.
Any more ideas?
