why so slow?

I've got two XP machines on my home network (linksys wrk54g) that I'm
moving ~14Gb of data between. Now, I don't expect the full 100Mb/s
throughput but it seems to be exceedingly slow. In about 12 hours, I've
moved around 1.9Gb which comes to about .337Mb/s.

Any ideas what the problem might be?

TIA,
David
