[LARTC] Latency in SFQ

Linux Advanced Routing and Traffic Control

Dear all...

If we are using TBF, we can reduce "buffer" and "limit" to minimize latency.
What should we do in SFQ?

I tried to use SFQ, but the latency goes up to 10.000 to 20.000  milisecond 
in case of overloaded.

Can someone help me?

I'm using cbq.init, and here is my configuration:

Parent class:
DEVICE=eth0,10Mbit,1Mbit
RATE=64Kbit
WEIGHT=6.4Kbit
PRIO=5
LEAF=tbf
BUFFER=3000
LIMIT=3000
BOUNDED=yes
ISOLATED=no

In child class:
DEVICE=eth0,10Mbit,1Mbit
RATE=16Kbit
WEIGHT=1.6Kbit
PRIO=5
PARENT=0500
LEAF=sfq
BOUNDED=no
ISOLATED=no
PERTURB=5
QUANTUM=3000
RULE=10.0.0.201

Regards,
Adi Nugroho
