Could you gather statistics about packet size too while you test?
Linux tries to delay small packets in tcp streams in the hope that
more data will follow. I would think the more sockets mldonkey spreads
it upload bandwith over the less successfull this becomes and more
overhead due to tcp/ip headers is produced and thus less speed.

A packet distribution by size graph could indicate such behaviour.
