arnobru Posted November 17, 2011 Report Share Posted November 17, 2011 Hi everyone,I decided to give utorrent server another try (I tried it when it first released but didn't find it stable enough) and it actually works quite well now on my debian server. I get pretty good rates throughout most downloads, reaching from 1,0 MB/s to 2,0 MB/s most times.The problem is that I only get a good rate from 0% to about 95% completion. When I get to 95%, the rate drops big time : about 20 KB/s to 50 KB/s until completion, thus taking 3 times longer to complete a download. This happers almost to all torrents.Any idea how to prevent that?Thanks! Link to comment Share on other sites More sharing options...
arnobru Posted November 17, 2011 Author Report Share Posted November 17, 2011 I just downloaded a 200MB debian iso to illustrate :[edit]full image here :https://lh4.googleusercontent.com/-ozttNNbthB0/TsTbyQH-K6I/AAAAAAAAA-I/LLMcESVxcV8/s912/graph.GIF Link to comment Share on other sites More sharing options...
DreadWingKnight Posted November 17, 2011 Report Share Posted November 17, 2011 Do you get the same behavior downloading something like slackware? Link to comment Share on other sites More sharing options...
arnobru Posted November 17, 2011 Author Report Share Posted November 17, 2011 I'm getting a steady 1,6 MB/s on the official slackware DVD torrent, i'll let you know how it ends when it does. why should it be different on that particular torrent?

DreadWingKnight Posted November 17, 2011 Report Share Posted November 17, 2011 Because piece availability is likely better on slackware in the final 10% than on the torrent you're having problems with. Link to comment Share on other sites More sharing options...
arnobru Posted November 17, 2011 Author Report Share Posted November 17, 2011 I see, i'll just wait and see then. ETA : 30 minutes. Link to comment Share on other sites More sharing options...
arnobru Posted November 17, 2011 Author Report Share Posted November 17, 2011 Ok, the donwload is done, the DL speed started dropping at about 97% and it only dropped from 1700 KB/s to 100KB/s, so not that big of a delay (10 minutes longer than estimated ), but still a speed drop as usual. Isn't there a setting that could cause that kind of behavior? Link to comment Share on other sites More sharing options...
DreadWingKnight Posted November 17, 2011 Report Share Posted November 17, 2011 Nope. It's all piece availability on the swarms. Link to comment Share on other sites More sharing options...
arnobru Posted November 17, 2011 Author Report Share Posted November 17, 2011 Well, one thing's for sure, when I download the debian iso on a windows version of utorrent, I get a steady 1,6 MB/s until the very end (I tried it several times, and the results are consistent) so I'm quite certain that the torrent availability isn't the problem here.

mcaspi Posted November 17, 2011 Report Share Posted November 17, 2011 If an uploader disconnects from you, chokes you or doesn't have pieces that you nedd, your download speed will drop. Don't know of a setting that can change this. Link to comment Share on other sites More sharing options...
arnobru Posted November 17, 2011 Author Report Share Posted November 17, 2011 If an uploader disconnects from you, chokes you or doesn't have pieces that you nedd, your download speed will drop. Don't know of a setting that can change this.I'm well aware of that possibility, but this behavior is systematic on uTorrent server whereas those speed drops never happen on uTorrent for Windows when downloading the exact same torrent (both my debian server and Windows pc being on the same network, using the same internet connection etc.). That tells me that there's something wrong with uTorrent server, wouldn't you agree? :| Link to comment Share on other sites More sharing options...
mcaspi Posted November 17, 2011 Report Share Posted November 17, 2011 I don't know if there's something wrong with uTorrent server. The only thing I know is that it can be investigated. If you are really curious about this you can check what client/s uploads to you at around 1.6M,you can log it/them etc. My instinct tells me that it's not an issue but I can be wrong.

arnobru Posted November 17, 2011 Author Report Share Posted November 17, 2011 The WebUI doesn't have a "Clients" tab, how can I monitor them? Link to comment Share on other sites More sharing options...
mcaspi Posted November 17, 2011 Report Share Posted November 17, 2011 Hmm, doesn't seem to be there. I am not a Linux user so I can't help with this so much. See what you can grab from the logger. Link to comment Share on other sites More sharing options...
arnobru Posted November 17, 2011 Author Report Share Posted November 17, 2011 yeah i'll see what I can do to monitor clients, if anyone knows something about this issue, I'm still open to suggestions. Link to comment Share on other sites More sharing options...

arnobru Posted November 18, 2011 Author Report Share Posted November 18, 2011 Hi,I installed the WebUI you mentionned, mit. I do get the peers tab on that one, so I ran some download tests with a high availability torrent. When the speed drops occur, it's not that I have less peers uploading to me than before, it's just that every peer has the upload speed dropping as well.For instance, when i'm at 90% completion, sorting peers by speed shows me that there are, say, 5 peers uploading at about 200KB/s, after the speed dropped, the top upload speed in the list is like 10KB/s although those peers all had 100% of the file.So, yeah, very weird behavior, abnormal i'm sure...

mit Posted November 18, 2011 Report Share Posted November 18, 2011 ..................................................................So, yeah, very weird behavior, abnormal i'm sure...Probably you are right.But what's the reason!?In cache maybe.......I think that I seen the same behavior to me,but i was thinking that is the advisedly.By the way,i also use Debian.

I'd sure like to know the reason I've been almost randomly changing settings in the advanced options with no luck... By the way,i also use Debian. Yeah, Debian's neat Link to comment Share on other sites More sharing options...
mcdonald Posted November 18, 2011 Report Share Posted November 18, 2011 The WebUI doesn't have a "Clients" tab, how can I monitor them?The web UI for the next uTorrent Server release will present peer lists for active torrents. Although that doesn't help you right now. Link to comment Share on other sites More sharing options...

shintorojin Posted September 14, 2012 Report Share Posted September 14, 2012 Hey not sure if this is still an issue, but could it have something to do with the file verification process as the file nears completion? Link to comment Share on other sites More sharing options...
