Well, the actual transfer occured around 145 - 150KB/sec according to the
ftp program, normally that is 160KB/sec, and the average is around
10-15KB/sec higher after you factor out at least ftp, tcp, IP, and
ethernet header. My bandwidth monitor dockapp shows around 176-164 when
it's working right, but now it starts really slow and eventually gets to
around the average you saw in the graphs.
