ICMC, I don't have anything other to add considering the good advice you already gotten, so all I can suggest is maybe try using a newer libtorrent, e.g courtesy of Nekotan for latest deluge 1.3.15: viewtopic.php?t=55168
Also, as said already, it's hard to know where you are in swarm, or how it was put. When I test something with a Linux ISO very popular and for sure properly connectable and unfirewalled, then often I don't upload for long time and when does, then also slow often, so it's sometimes hard to know if normal or not, though if you're connectable and unfirewalled, as you already tested properly, then it should work though. .
