I think I found your problem.

If you're trying to push ~20GB between two machines through four unswitched 
(and I presume 10base-T) hubs, then, yeah, it's gonna collide like a SOB and 
take 31 hours.  At the very least, get the two machines on the same hub, but, 
better yet, put a 10/100 switch in place.  Just because the four cascaded hubs 
works doesn't mean it works efficiently.  The latency is just going to be awful.

I routinely push large files and large quanitities of files around on my home 
LAN, which has two 10/100 switches connected via a long crossover cable.  A 
machine on one switch and a machine on another can manage 7-8MB/sec and I know 
I'm taking a hit there on account of the latencies between the two switches.
