I am running HTB on a PowerPC = platform and=20 using following script to do rate limit.

When I set rate of class 1:11 lower = than=20 4mbit, I can get traffic rate = close to=20 the setting.

However, if I set the rate higher = than 4mbit,=20 I will get much

lower bandwidth (roughly 4.5mbit) = than the=20 setting, no matter how big the = setting=20 is.

To verify the script, I run it on PC = with then I got correct result.

Could anybody give me some = hints?

Thank you

Dennis
