Both, depending on your connection. True: lots of uploading can kill your download speed (data has to pass through the same wire). False: BT works by trading pieces of a file in your queue with other users. You don't trade, you don't get any.

Well if he got ADSL, and he's downloading at 90% upload capacity he will only get 10% of his downstream capacity.

On the other hand, capping ur upload speed on ur torrent, in my case azureus, won't interfear with the my download speed.

peers favour other peers that upload to them. When you start leeching a new torrent you have nothing to offer to other peers and they will tend to ignore you. This makes the starts slow, in particular if, by change, the peers you are connected to include few or no seeders. The download speed should increase as soon as you have some pieces to share.

Check the color of his torrent too. Must be green. Ofcourse.

Good for me I signed up on some torrent sites on time, with mindboggling download speed. New releases=400Kb/sec

The upload speed affects the download speed in essentially two ways:
  • Bittorrent peers tend to favour those other peers that upload to them. This means that if A and B are leeching the same torrent and A is sending data to B at high speed then B will try to reciprocate. So due to this effect high upload speeds lead to high download speeds.
  • Due to the way TCP works, when A is downloading something from B it has to keep telling B that it received the data sent to him. (These are called acknowledgements - ACKs -, a sort of "got it!" messages). If A fails to do this then B will stop sending data and wait. If A is uploading at full speed there may be no bandwidth left for the ACKs and they will be delayed. So due to this effect excessively high upload speeds lead to low download speeds.
The full effect is a combination of the two. The upload should be kept as high as possible while allowing the ACKs to get through without delay. A good thumb rule is keeping the upload at about 80% of the theoretical upload speed. You will have to fine tune yours to find out what works best for you.

check your ports.... ports dont effect outgoing but they do effect incomming.

if your router is uPnP azerues will open the port automatically
