Well, i had real experience on HTB, when i set too short buffers on  my QoS 
qdiscs, the incoming rate jumped too high than overall. When i set larger 
buffers (and by the way dropped sfq and use bfifo) - it is dropped.  No idea 
why, bug or specific things in  protocols congestion control. Maybe worth to 
try...
