Nefarious Posted October 16, 2006 Report Share Posted October 16, 2006 I was just downlaoding a single file torrent and i noticed this behavior on it:is it possible that some client is prioritizing the las pieces of the torrent? i didnt know of any client that could do that, at least not that wayor is it just a coincidence...it is a 4GB file, so seems all the prioritized is like 1 GB, too much for a coincidence i think Link to comment Share on other sites More sharing options...
Ezra Posted October 16, 2006 Report Share Posted October 16, 2006 Maybe you have prioritize first and last pieces enabled? Link to comment Share on other sites More sharing options...
Ultima Posted October 16, 2006 Report Share Posted October 16, 2006 That's irrelevant in this case, as downloading first and last pieces do not affect it to that extent. IMHO, it's entirely coincidence. Link to comment Share on other sites More sharing options...
torrero Posted October 16, 2006 Report Share Posted October 16, 2006 I was seeding two torrents with just one mp3 file each. The torrents were both 3 month seeded, so there were only a few peers. A guy with libtorrent jumped on both torrents and its download behaviour was like OP explained. So chances are its a libtorrent client. Link to comment Share on other sites More sharing options...
Nefarious Posted October 17, 2006 Author Report Share Posted October 17, 2006 just to be safe i'm gonna make a re-check, let it not be a wasted download edit: nope, still like that, libtorrent then... hmmm will take a look at it Link to comment Share on other sites More sharing options...
Harry Poppins Posted October 17, 2006 Report Share Posted October 17, 2006 I'm not sure I get what's going on here, if those solid blocks were in the availability bar, it would mean that the swarm has more copies of those particular files/pieces than the rest (right?). But they're in the "downloaded" bar, meaning that your client downloaded them first, probably because you prioritized those files (is that the case?). If I interpret those bars correctly, then the availability seems to be pretty evenly distributed, so there's no reason for your client to download those particular files first, unless you prioritized them, or by some freakish convergence of factors that my tiny mind fails to grasp.

Ultima Posted October 17, 2006 Report Share Posted October 17, 2006 It's a 1 file torrent, which is the semi-odd part. It'd make some sense if there were a bunch of small files, and you prioritize first and last pieces, but since that's not the case... Link to comment Share on other sites More sharing options...
Harry Poppins Posted October 18, 2006 Report Share Posted October 18, 2006 Oh sorry, I should have ready more carefully. That does look weird... Link to comment Share on other sites More sharing options...
Ultima Posted October 18, 2006 Report Share Posted October 18, 2006 lol don't worry about that, I made that same exact mistake in reading the first post the first time around... ICleolion had to correct me :< Link to comment Share on other sites More sharing options...
Alpha-Toxic Posted October 18, 2006 Report Share Posted October 18, 2006 I think this is "allways prio rare" at work here. There are lots of clients that tend to prio the beginning of the torrent, either if u tell them to (like BC) or automagicaly (like KTorrent). If u ask me, the end of the availability bar does look whiter, the difference might have been even bigger earlier. So uT is prioritizing the rare pieces and u have what u see. And what I think is a proof to that is the single piece at the right side with a bit higher availability that uT hasn't dl-ed. Link to comment Share on other sites More sharing options...
Ultima Posted October 18, 2006 Report Share Posted October 18, 2006 Prioritizing rare pieces wouldn't have that great an effect as to make the piece distribution extremely consolidated and dense there, though. I still say it's a coincidence (along the lines of what has been suggested -- outside interference and/or stupid clients screwing around). Link to comment Share on other sites More sharing options...

Switeck Posted October 18, 2006 Report Share Posted October 18, 2006 There may be a sort of "light" super-seeding/initial seeding mode in libtorrent which basically only uploads the upper half or lower half of a torrent. This would only be of value in very slightly reducing piece reequests and piece list exchanges between peers and seeds. Link to comment Share on other sites More sharing options...
