There's a problem in my country (don't know somewhere else), mt service provider limit our connection. I subscribe 1mb, but when the download speed more than 100 kbs my bit comet will hang. When I set upload high, my download will drop not more than 10 kbs. I have no choice, but still I left a few torrent to run after finished download. I even upgrade my pc's cooling system, and let it on for 2-3 days, sometime 4 days just for you all upload the file while I'm downloading. My electrical bill is up, but I'm satisfied with what I provide and what I get.
