Yep its the former... pushing and pulling from the same Windows PC which 
is a P4. The linux server is a PIII....i delete the 350MB file from the 
source/dest in turn in order to try it...

Both CPUs reach a max of 2-3%, so the bottleneck is somewhere else...

I know, but I'm trying to simulate transfer over an internet conncetion 
on my lan first.
I'll experiment further and let you know what I come up with... but I'm 
quite sure its something particular to my setup.

Thanks wayne!
