GreenJ Posted December 5, 2009 Report Posted December 5, 2009 I have 1 mbit upload. This should equate roughly to 120kB/s. If I set my upload limit to 100kB/s and try to saturate my upload with a test torrent, it maxes out around 45kB/s, NOT 100kB/s! What the hell is going on? If I increase the upload cap to 400kB/s then all of a sudden I can get 100kB/s of true upload. What is even more odd about this is that the upload cap needed to maintain a true upload of 100kB/s changes based on how many torrents are active.Help?
Switeck Posted December 5, 2009 Report Posted December 5, 2009 It could be a version-specific error in uTorrent...and/or BAD utorrent settings!
GreenJ Posted December 5, 2009 Author Report Posted December 5, 2009 Here's the thing though... I've had this problem before on previous computers but never this bad. If I run a speed test and a bandwidth monitoring program, the program says I'm uploading around 300-400kB/s while the speed test says that I'm at 120kB/s. I think that there is something seriously wrong with windows here but I have no idea where to start or how to get more information related to this problem.
Switeck Posted December 5, 2009 Report Posted December 5, 2009 The speed tests may be "confused" by your ISP's very short-term max burst speeds.uTorrent needs to know the sustained speed.
GreenJ Posted December 5, 2009 Author Report Posted December 5, 2009 Well how would you suggest I go about doing that. The sustained speed is 120kB/s and if I cap it at 100kB/s I absolutely will not ever be able to approach that limit in utorrent. It will just diddle around at 40-50kB/s.
Switeck Posted December 5, 2009 Report Posted December 5, 2009 Did you mention what possibly buggy version (and build number) of uTorrent you were using?And what uTorrent settings are you using as shown by Speed Guide (CTRL+G) and any advanced settings you change from default?As for me, rate limiting works fine:http://img185.imageshack.us/img185/8845/utorrentpyramids.png
GreenJ Posted December 5, 2009 Author Report Posted December 5, 2009 I'm using the latest stable version. 1.8.5 build 17414. Using the standard speed guide settings for a 1mbit upload line. Another thing I notice is that if I try to upload a few torrents and download a few simultaneously, they both have HORRIBLE speed. If I stop all of the downloads then the uploads do fine and vice versa. This is so buggy... It also appears that rate limiting works perfectly as long as I am only uploading and not downloading whatsoever.
Switeck Posted December 5, 2009 Report Posted December 5, 2009 Reduce connections per torrent, disable Resolve IPs and DHT, lower upload limit a bit.
GreenJ Posted December 6, 2009 Author Report Posted December 6, 2009 Wow... it's actually looking a bit better. I'll keep an eye on it and let you know how it goes. Thanks.Uhg... I'm getting problems now where I'll add a torrent and it wont start unless I exit and restart the program. The trackers just stay at updating and never resolve/update.I am also back to square one. 8 torrents seeding, maxing out my line at 120kB/s upload. As soon as I cap it to 100kB/s the total traffic drops down to about 60kB/s. Uncapped it comes right back up. What can I do?
