nathalas Posted April 22, 2010 Report Share Posted April 22, 2010 Hi there. I have been plagued by uplink speed problems lately since going utorrent 2.0I've finally found the issue.Heres the background, I got a WRT54GL router with custom firmware modified to be able to handle P2P well.I have a 60/60mbit connection that speed tests with various providers to that speed fully, no problems, and I can both download and upload at that speed in any forms of tests.I have an ftp server running on the machine, besides utorrent. Now the exciting part awaits, if utorrent is running, with no active torrents of any kind, with bandwidth management enabled (uTP..), then my ftp server's upload is hampered severely such that a person downloading at 2.5MB/s through the FTP server, would be limited to 400KB/s per thread roughly. If I turn off bandwidth management, immediately his speed will increase back to full throttle.This does not seem to be in sync with the idea of uTP, that is to prevent BitTorrent to impair other applications. So, this problem is not with the upload speed in utorrent, but the upload speed in other programs while utorrent is open and completely inactive.I've thoroughly tested it, and I've had many other people experience the same simultaneously, they all had instant increase in their download speeds from my other processes the second I turned off bandwidth management.

Firon Posted April 22, 2010 Report Share Posted April 22, 2010 Are you running DD-WRT? Because DD-WRT is a piece of shit. Link to comment Share on other sites More sharing options...
Ultima Posted April 23, 2010 Report Share Posted April 23, 2010 if utorrent is running, with no active torrents of any kind, with bandwidth management enabled (uTP..)O_oAre there connections open? Any overhead in the Speed graph? Link to comment Share on other sites More sharing options...
rafi Posted April 23, 2010 Report Share Posted April 23, 2010 this reminds me of a similar post of mine in the 2.01 thread: http://forum.utorrent.com/viewtopic.php?pid=474594#p474594sadly - I don't think anyone have responded to it oh, and Firon, I don't have a crappy router or DD-WRT installed ...

nathalas Posted April 24, 2010 Author Report Share Posted April 24, 2010 No, I use tomato with the RAF mod, and I've observed the same behavior using a completely different router (dlink 655)It would be interesting to observe if the behavior persists without a router in the middle.However, this is really irrelevant, I open utorrent with absolutely no active torrents, why on earth should it be limiting bandwidth on other applications?Ultima: I will set up another test where I keep tabs on the overhead graph in utorrent and the info given off by the router in terms of connections, realtime bandwidth etcetera, and post back.

Firon Posted April 24, 2010 Report Share Posted April 24, 2010 It has no control over your other applications. µTorrent can only limit itself. The only way you could see other applications being limited is if your -router- was doing that. Link to comment Share on other sites More sharing options...
nathalas Posted April 24, 2010 Author Report Share Posted April 24, 2010 Firon:What is utorrent doing when the torrent list is empty and uTP is enabled, that affects my routers performance so severely? I realize that it does not obtain control over my NIC and assign bandwidth priorities or anything, Im just pointing out the issue I've run into - If I have no activity in utorrent, then why does turning on and off uTP make such a *huge* impact on my per-thread speed as delivered by the router or otherwise?

Switeck Posted April 24, 2010 Report Share Posted April 24, 2010 Do you have DHT (both kinds) disabled?That alone bloody kills weak routers. Link to comment Share on other sites More sharing options...
nathalas Posted April 25, 2010 Author Report Share Posted April 25, 2010 Switeck: I have DHT enabled, and my speeds are unaffected by it, even during heavy torrent activity my upstream from the ftp server persists in delivering excellent speeds.The sole feature that affects my speed is uTP, no change was observed from any of the other features being disabled. Remember that this is with no torrents active in uTorrent, completely clean. Link to comment Share on other sites More sharing options...
Switeck Posted April 26, 2010 Report Share Posted April 26, 2010 If disabling uTP (Bandwidth Management in Preferences, BitTorrent) solved your problem, then quite likely the router's just bad. Link to comment Share on other sites More sharing options...
nathalas Posted May 10, 2010 Author Report Share Posted May 10, 2010 So by enabling uTP, uTorrent immediately proceeds to kill my router with a completely empty torrent list? Is this as intended that uTP actually performs anything when there is really nothing to perform?And why does it kill my router when there is no traffic, when regular heavy duty torrent traffic does not?

Switeck Posted May 10, 2010 Report Share Posted May 10, 2010 Were there no incoming connection attempts for torrents you ONCE had? Link to comment Share on other sites More sharing options...
