Quantum must be > 1500 so the internal caculations of htb are good.
And 60.000 is the maximum hard coded in htb.
So try to take r2q so
smallest_rate/r2q > 1500
biggest_rate/r2q < 60000

Quatum is only used if you have a parent class that''s has remaining
bandwidth.
I don''t know if this is the case in your situation.
