I followed all the advice here. I am running on a 1.5Mbps DL/256Kbps UL connection. Here are my current settings:

Max Downloads: 12
Download Bandwidth: 100%
Upload Bandwidth: 26.69KBps
Uploads Per Person: 2
Max Upload Slots: 3

I am downloading consistently between 30-50KBps. I'm wondering if this is the best i can hope for, or can i improve my DL speed even more?
