[LARTC] htb quantum/r2q problem/question

[Ciprian Niculescu]

hello,

i have a config that is with a large domain of rate, from 2kb to 40Mb 
and i have some problems with i don't know how to deal with.

so here are some classes 2 with q\x1000, one with q 200000 and one with 
qd00, all have been calculated by htb, in the code i speficien just 
rate,ceil, no quantum, no r2q, no bursts
($tc class add $IF_INT parent 1:2 classid 1:21 htb rate 
${eth1_web_r}kbit prio 1)

class htb 1:199 parent 1:10 leaf 1990: prio 2 quantum 200000 rate 
23000Kbit ceil 47040Kbit burst 10Kb/8 mpu 0b cburst 61800b/8 mpu 0b level 0

class htb 1:2 parent 1:20 prio 1 quantum 1000 rate 48Kbit ceil 48Kbit 
burst 10Kb/8 mpu 0b cburst 1660b/8 mpu 0b level 0

class htb 1:12 parent 1:10 prio 1 quantum 1000 rate 50Kbit ceil 
48000Kbit burst 10Kb/8 mpu 0b cburst 63025b/8 mpu 0b level 0

class htb 1:15 parent 1:10 prio 1 quantum 6400 rate 500Kbit ceil 
48000Kbit burst 10Kb/8 mpu 0b cburst 63025b/8 mpu 0b level 0


and in the logs o get:
kernel: HTB init, kernel part version 3.17
kernel: HTB: quantum of class 10001 is big. Consider r2q change.
kernel: HTB: quantum of class 10002 is small. Consider r2q change.
kernel: HTB: quantum of class 10012 is small. Consider r2q change.
kernel: HTB: quantum of class 10199 is big. Consider r2q change.


for now i put manualy 1500 to all, but more logicaly how do i set the 
quantum, what are the considerations????
