Thanks for your help,
it's working with 110k for entire bandwidth and fluent downloading via ftp.
In real environment, one of the 2 classes is for terminal connections
(Citrix-ICA protocol), therefore the load is not stepless and getting in
ballance (according to classes) is not quick enough(= it's in my opinion, no
practice tests).
Shall I speed up the time by any change in config script (different qdisc,
smaller burst,....)?
Thanks

Hi it seems as if there is something other throttling
the data - is not it the case that you tested the downloads
thru your 128k internet connection ? If yes then throttling is
done at other side of line. The try to set BAND to 110k for
example ...
