You mean the machine is bogging down or your outside connection is getting bogged down? I think the ftp session is taking your entire fractional T. I don't think it would be slowing down your machine too much. IPFW I *think* has rate shaping ability. You might be able to add rules to set ftp to a certain bandwidth. I am now going beyond my experience, I haven't tried to rateshape on a freebsd box yet.
