I'm using utorrent, and if I download a fairly popular file with lots of seeders I can usually get 100-200kB/s download. However, my uploading to other users is really slow. I've never seen a sustained upload rate of more than 4kB/s for a single file, and I rarely break 10kB/s for all of my uploads combined. I probably average about 0.5kB/s uploading. Is this a port or firewall problem of some sort, or do I just have a bad internet connection? Anything I can do to help fix it?
