Peer selection and downloading


Recommended Posts

I've got a perfectly set up XP system with uTorrent (v1.3 and 1.4), NAT works like a champ, with 20KB of my upstream reserved for uploads (Comcast 4M/384k).

As I've got an XP box, the iLife 06 files are useless to me, but the torrent has one characteristic that struck me as interesting, in that there's over 10,000 leechers as I type this, with about 20 seeds, and the file is a large 6GB.

As I understand the Torrent process, the 20 seeds will try to get peers to evenly distribute the file parts, and then share among themselves.

After 2 days, I'm currently sitting with a share ratio of 2.003, with 16% of the file complete.

uTorrent stopped responding sometime today, and when I started it back up I was able to "make up" ground at tolerable (if a little slow) rates of ~70k/sec.

Looking at the peer list, we're all at 16%, every last one of us. It's like my uTorrent is more interested in getting a torrent spread out than it is getting it downloaded. This theory is further supported since I'm currently uploading at 22k/sec, and not downloading at all.

Something's up with the logic here...

if all people is at same downloaded rate, it means the seeders are really slow or have some problem with the files.

is not utorrent's fault u are not downloading anything since the other peers in the swarm doenst have pieces that u need as u all have the same completed pieces, however as people try and get the file starting from 0% its obvious that your upload will go up to those persons.

i wanna know what u mean by 20 seeds? it means u are connected to 20 seeds? or the tracker is reporting 20 seeds even if u havent connected to any, sometimes tracker say bad peer reporting (I have a few torrents that claim 24 seeders even if there is only 2 or 3 i can connect with)

It was 20 seeds reported by the tracker, the number steadily increasing day over day.

I don't accept that 10,000+ hosts all have exact the same pieces when new seeds are appearing.

At the _very least_ the anti-snubbing algorithm would stop uploading (except for optimistic unchoking), and I'd get new peers with parts I don't have within the tracker update time.

If that were the case, I wouldn't have a ratio of over 2:1 and be 16% done.

I'm not pointing fingers here or tearing down uTorrent, I'm reporting a bug.
