[expert] Data Collision - How to improve transfer?

[Sevatio Octavio]

I know this is not really a Linux issue but...

I'm transferring data between my linbox and winbox.  Both are equipped with 10/100 
NICs through a 10/100 hub.  My max transfer rate
stops around 600k/s and my hub's collision light stays on for the majority of the time 
during transfer.  Is there any way to improve
this transfer rate by cutting down the data collision?
