Alright. I suggest you do some measuring, to find out your real rates, 
and set HTB rates to be slightly lower so that you are the bottleneck. 
Most likely you'll have to experiment a little until you find the best 
setting for your setup.

Actually, I specify the quantum directly, with 'quantum $MTU'
for every class. I don't know wether that's a good thing or a 
bad thing, but it worked very well for me, and seems to work 
well for others... at least nobody reported a problem to me so 
far that could be traced to be caused by this quantum setting.

It should not be smaller than your MTU, and not too big.

With a huge difference in rates (100Mbit vs 64kbit) there is no r2q 
that will fit all classes. So there is no other way as to set quantum 
directly at least for some classes (and I set it for all...).
