Stef and all,
I got error sometimes, dmesg results like this:
HTB: quantum of class 10011 is small. Consider r2q change.<4>HTB: quantum
of class 10012 is small. Consider r2q change.<4>HTB: quantum of class
10013 is small. Consider r2q change.<4>HTB: quantum of class 10014 is
small. Consider r2q change.<4>HTB: quantum of class 10015 is small.
Consider r2q change.<4>HTB: quantum of class 10016 is small. Consider r2q
change.<4>HTB: quantum of class 10017 is small. Consider r2q
change.<4>HTB: quantum of class 10018 is small. Consider r2q change.<4>HT
Is this happened because i set QUANTUM value too low ?
i set 1000. Why it cannot set below MTU size (1500) ?
Regards,
Rio Martin.

Quantum is the number of bytes a class can send if it borrows unused bandwidth
from the parent. If it's 1000 and the packet size is 1500, the internal
calculations of htb can be f***ed up. You send 1500 but only 1000 is
counted.
