Yes, it's Kb (kilobits). I was extra careful with that. I also tested  
everything
with priority 1, and w/o setting the priority explicitely at all, both in
cbq and altq cases. I haven't tried hfsc yet.

In my case, as soon as allowed bandwidth for ftp "cuts" into what  
transfers I can
normaly achieve without queuing (or pf enabled), it all stalls.

Thanks for suggestions. I'll try testing with netcat, in addition to  
different
nics and maybe testing within single host as well, on two loopback  
interfaces.
In a few days though (long weekend here now, heh).
