Cool... here is how I tried to optimize the traffic:

helper () {
        ...
        iptables -t mangle -A $CHAIN -p tcp -m tcp --sport 80 --source my-domain.com -j MARK --set-mark 0x2
        iptables -t mangle -A $CHAIN -p tcp -m tcp --sport 80 -j RETURN
        ...
}

OPR=start CHAIN=OUTPUT helper
OPR=start CHAIN=PREROUTING helper

tc_helper () {
        ...
        tc qdisc add dev ${WAN_IF} root handle 1: htb default 15 r2q 1
        tc class add dev ${WAN_IF} parent 1: classid 1:1 htb rate ${UPLINK} ceil ${UPLINK} burst 6k
        tc class add dev ${WAN_IF} parent 1:1 classid 1:10 htb rate 64kbit ceil 64kbit prio 0
        tc class add dev ${WAN_IF} parent 1:1 classid 1:11 htb rate 64kbit ceil ${UPLINK} prio 1

        tc filter add dev ${WAN_IF} parent 1:0 protocol ip prio 1 handle 1 fw classid 1:10
        tc filter add dev ${WAN_IF} parent 1:0 protocol ip prio 2 handle 2 fw classid 1:11
        ...
}

WAN_IF=eth2 tc_helper

Please tell me if you need more information.

Thanks,
