Hi!

I have configured traffic shaping with = htb and imq=20 but when i am downloading the latency for example on the Bnet class is = very high=20 .....

example:

65 kb/s download

best latency: 56ms

lateny on bnet class = while downloading: 400=20 350 250 350 400 100 300 200 80 200 300 250 .....

To get informations about latency i am = marking ping=20 packets with iptables.

I want to play during other users = downloading=20 and i want to keep my voicechat useable ... i need = low latency

It would be nice if you could help = ...=20

I am happy about every answer = :)
