Make sure Transmission's port is forwarded. If this is not done, others cannot connect to you, and thus your speed will be hampered. -
You also need to ensure you cap your upload speed to about 60-70% of its maximum. eg if your upload connection is 256 Kilobits/sec, then you should enter 21 ((256 /8) * 0.66). This can be adjusted in the Bandwidth pane of Transmission's preferences on Action menu. +

Ultimately, the speed you get depends on the quality of the peers you are downloading from. If they have dial up connections, you are only going to be able to download at dial up speeds. Furthermore, if there are few seeds and many peers, more people will be fighting for the same scarce pieces and thus will slow things down. Best results are achieved when the torrent has more seeds than peers. Finally, you can only download what others are willing to send to you, and if they don't have it, they can't send it.
