Your setup is good, but you put all packets coming from computer A (and marked
with 1) in class 1:1. The problem is that this is not a leaf class because
it has a child class. And a non-leaf class can not transmit packets itself.
So the packets are sended at link speed.
Solution : only leaf classes can shape traffic so make sure all packets ends
up in a leaf class. You can do this by removing the filter statement so all
packets are placed in the default class. Or change your filter statement so
all packets marked with a 1 are redireted to class 1:19.
If you are interested, I did some tests myself. You can find the results on
www.docum.org.
