Hi,


I am having a problem where it appears that the queue speed is 1/10th of
the desired number. I have this simple setup on a bridge and can not get
any more than about 1700 Bps with a http download (roughly 12Kbits).

 altq on sis0 cbq bandwidth 256Kb queue { std_in }
 queue std_in    bandwidth 128Kb  cbq(default)
 
 pass  out on sis0 proto tcp from any to any queue std_in


It looks very much like the bandwidth number in the kernel is screwy.
