Using to much Upstream?

I dont really use that much bandwidth these days
a few torrents once in a while

For some reason ive been feeling sort of conned having 20 Mbit upstream and not using it most of the time
and being that qos works so well on atleast my eci modem

I have left a torrent seeding the last week or so just to see the result
The torrent doesnt manage full speed alot due to most of the peers being in australia and such
and there being a limited ammount of peers on the torrent
