Which I've done ;)) You said that in the comments of the "tc"
commands (you say that the priorities of the sibling classes should
be lower).

OK, I understand now. Thanks a lot :)))

That's something I learnt even when I didn't know about
wondershaper ;) My ADSL has 300kbit of upload rate, that's why I'm
using 256 and not 300. I want to leave those 44kbit for the other
box. BTW, I didn't notice that the other box was up and running
(running WinDOS) is uploading traffic at almost 10kbps so it is
probably filling the ADSL router buffers :( That may be the reason
why I'm getting poor latency when the ADSL FTP traffic goes above 175
(in fact, I bet the traffic limit is 300kbit-otherboxkbit).
Unfortunately I cannot shutdown that box by now, and probably I
will need to do my shaping taking into account an upload rate from
the other machine of about 12kbps or something like that. 15kbps will
be better... That leaves a value nearer to 180kbit instead of 256...
Well, I'll try to make the other box upload at a lower rate if I can.

But it gives me some improvement, why should I get rid of it?
I'm not sure about why it does, but using a burst of 8192-20480 and a
cburst of about the half seems to improve latency a bit. It's just an
illusion? For me it would be great if I could get rid of the burst
and cburst settings, because my tc script will be easier to maintain.
Thanks a lot for your help, now my tc works much better :))
