Do you have any errors in dmesg? And how is the memory and cpu usage ?

No. But maye you can create 1 super class (but I don't think it will change a
lot) :
root qdisc 1:0
class 1:10 rate = 8mbit = ceil
class 1:1 rate = 256 = ceil
class 1:2 rate = 192, ceil = 256
class 1:3 rate = 64, ceil = 256
class ....
