Hi,
got a 25/25Mbit connection which is quite stuffed. So I applied htb rules.
Uplink:

1:10 is icmp, interactive and http, https
1:30 is P2P as detected by ipp2p
1:20 is the rest
As you can see 1:10 hasn't even dropped a packet. Though when I ping the
our Internet gateway I get terrible packet loss, at least 10%. But why,
I don't see any packets dropped in 1:10?
Downlink:

1:20 is everything except P2P
1:30 is P2P as detected by ipp2p
I know I should be using ingress here, but I'd like to get the uplink
working first and this still helps throttle the P2P down. Also notice
that 2:20 hasn't dropped any packets.
I have only specified prios which as I understand don't really matter
ATM. I haven't touched quantums nor bursts, only rates and ceils. But I
don't think these problems are caused by this alone. What am I missing?
Also with the current configuration uplink nor downlink go near 25Mbit,
so I there should be free bandwidth.
The qos commands are as follows:
RATE_TOTAL="24500kbit"
QUANTUM_BIG="20000"
RATE_HIGH="7500kbit"
CEIL_HIGH="10000kbit"
RATE_DEFAULT="10000kbit"
CEIL_DEFAULT="20000kbit"
RATE_P2P="3000kbit"
CEIL_P2P="3100kbit"

tc qdisc add dev eth1 parent 1:20 handle 20: sfq perturb 10
tc qdisc add dev eth1 parent 1:30 handle 30: sfq perturb 10
Please point me in the right directions.
