Is there anything or any reason anyone can think of that would keep my 
machine from using its full capacity bandwidth?  Its a 3.4REL machine using 
a 10/100 BT NIC plugged into a 10/100 switch and it transfers almost like 
its on a 1 BT connection =P  It is absolutely driving me crazy!  Im using 
the Via Rhine driver (DLink card) and no NATD or ipfw.  Here is what 
systeat -tcp gives me:


                  /0   /1   /2   /3   /4   /5   /6   /7   /8   /9   /10

Is there a way for the ftp daemon to throttle its throughput?  Because this 
problem is *most* apparent on incoming ftp sessions for my users.
