I just tested with my script and also see a 5-8% advantage for the lower handle class.
I wouldn't call it a bug though - HTB is written for high traffic setups and trade off needs to be made between perfect behaviour and CPU usage and you say it gets better with more classes.

Well - you had 5-8% while I noticed 50-80% difference! (user1 ~76kB/s and user3 ~45kB/s).
Of course - as you can see on the graph I created: with more classes difference beteween u1&u3 is smaller...
Can you send me the script you used for your test which gave you only 5-8%? Maybe there is something wrong with the one of mine?
