Hi,
i have just run a test locally (on a 4.2R system, queues with weight
1 and 10, transfers on different tcp port) and the results
are exactly what one would expect -- one flow gets 10 times the bw of the
other one.
So i believe you have done some mistake in your config or your
measurement (e.g. some other bottleneck in the net limiting
one flow to 60Kbit, leaving a full 60k to the other no matter how
weight are assigned).
Note that running this kind of experiments requires a bit of care --
with a 10:1 speed ratio, one of the transfer might complete much faster
than the other leaving full bw to the the other flow for 90%
of the time, which in the end causes both flow to show
approx the same speed.
cheers
