[LARTC] HTB and bittorrent, won't work

[Edgar]

Hi, thanks for your help and interest, someone told me about that already, so 
I did it, and this is the script I'm running to do it:
#!/bin/sh

### ERASING RULES AND USER CREATED CHAINS ###
iptables -t mangle -F
iptables -t mangle -X
iptables -t mangle -N lay7PRE
iptables -t mangle -N lay7POST

### PREROUTING RULES ###
iptables -t mangle -A lay7PRE -j CONNMARK --restore-mark
iptables -t mangle -A lay7PRE -m mark ! --mark 0 -j ACCEPT
iptables -t mangle -A lay7PRE -m layer7 --l7proto bittorrent -j MARK 
--set-mark 1
iptables -t mangle -A lay7PRE -m layer7 --l7proto smtp -j MARK --set-mark 2
iptables -t mangle -A lay7PRE -m layer7 --l7proto http -j MARK --set-mark 3
iptables -t mangle -A lay7PRE -j CONNMARK --save-mark

### POSTROUTING RULES ###
iptables -t mangle -A lay7POST -o eth1 -m mark --mark 1 -j CLASSIFY 
--set-class 2:2
iptables -t mangle -A lay7POST -o eth1 -m mark --mark 2 -j CLASSIFY 
--set-class 2:3
iptables -t mangle -A lay7POST -o eth1 -m mark --mark 3 -j CLASSIFY 
--set-class 2:4

### ------------------------------------------------------------------- ###
iptables -t mangle -A PREROUTING -j lay7PRE
iptables -t mangle -A POSTROUTING -j lay7POST

I'm trying this right now, and I believe its kind of working, but web surfing 
is very slow, I might say unusable, so this is not what I want, also I had to 
mark http traffic to make this work, give it a higher prio in htb, so I 
believe I'm missing something else? someone suggested to add a new class for 
ACK packets, I've done that already, but I've only noticed little 
difference... really don't know whats happening, if you don't have tcng I can 
show you my tc rules (showed by tc -s class show dev eth1). Thank you again
