Hello everyone.

I use shorewall with support for traffic shapping. Im using version 3.2.4.

When I dont have QoS activated in shorewall I can make downloads at
950KBytes/s, but when I have QoS activated (TC_ENABLED=Internal) I can
just make downloads at 750KBytes/s and they are very unstable.

I dont know what I am doing wrong. I have a internet cable connection
with 8Mbits/s   of downstream and 384Kbits/s of upstream.

Here it is a simple configuration files that I am using (they are very
simple because im trying to debug the problem):


tcdevices:
#INTERFACE      IN-BANDWITH     OUT-BANDWIDTH
eth0            8mbit           384kbit

tcclasses
#INTERFACE  MARK    RATE         CEIL       PRIORITY        OPTIONS
eth0        1       full/9       full          1            default

tcrules:
here i dont have anything.



It seems that when I activate the QoS I loose download speed ant is very
unstable.

Example - With QoS
wget

ftp://ftp.telepac.pt/pub/slackware/slackware/slackware-10.2-iso/slackware-10.2-install-d1.iso
           => `slackware-10.2-install-d1.iso'

As you can see just 715KB/s

Now without QoS(TC_ENABLED=No)
wget
