Probably this is an old question, but i'm not able to find nothing about...
So, i've just started to play with tc to limit the transfer speed to my
hdsl connection. I'm using the tbf and the command
# tc qdisc add dev eth0 root tbf rate 10kbit latency 50ms burst 1000
Then i've tried to transfer a big (20 Mbyte) file onto my lan, using ftp
and the client (ncftp) is saying that the average transfer speed is
39.71 kB ( around 400 kbit). What i'm missing ?
Thnaks in advance

you are shaping outgoing traffic: so if you want to give it a try you
must upload!
to shape incoming traffic you need either ingress qdisc or IMQ : have a
look at LARTC.
you are downloading at 300kbit, by the way: 39.71*8
