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.
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.
