Also remember that if using SFQ on leaf qdisc, then the queue length may cause delay problems if it's too long (default is 128). Changing this to 32 for rates below 100kb/s, I have found to help things considerably. This change needs to be done in linux/net/sched/sch_sfq.c. which also needs a kernel recompilation.
Hmm,
When I use sfq with cbq at speeds like 256Kbit there is no problem at all, runs very sweetly, but with HTB and sfq, it is very jerky and poor. I'll try the change in pkt_sched.h first and see how I go...
Ok, I tried the change in pkt_sched.h and didn't notice any difference whatsoever. Any other ideas ? cbq is still fine but htb for the same speed is very jerky and the speed fluctuates around 60-80% of the wanted speed, while cbq gives a steady 99% of the wanted speed...
