G. When the speed is going over your set limits:
a. See that your Perf.->bandwidth->Apply rate limit to uTP connections is checked...
b. Optionally: Enable Preferences->bandwidth->Apply rate limit to transport overhead
c. Enable Preferences->BitTorrent->limit local peers bandwidth
d. DHT network can 'contribute' some upload rate. If you do not really need it, you can disable it, to avoid that:
Either completely - disable Preferences ->Bittorrent->Enable DHT network, or for individual torrents - in properties of the torrent.
