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.
