Skychaser Posted June 17, 2008 Report Share Posted June 17, 2008 I have a speed-issue that boggles me. If I limit the DOWNLOAD speed on a torrent, the upload speed drops too, to roughly 50% of what it was before, when download was set to unlimited. If I do this on a per-torrent basis, only the upload for that torrent drops, if I do it globally the total uploadspeed goes down.Example. With both upload and download unlimited, I download at some 250 kB/s (which is my max) and upload at 350-400kB/s. When I limit the download to 200kB/s, to have some bandwidth available for browsing, the upload goes down to about 200kB/s too. If it were the opposite (limit upload drops download), that'd make sense to me, but this... Any idea anyone? Some sneaky advanced setting I overlooked?

Switeck Posted June 17, 2008 Report Share Posted June 17, 2008 How come can you upload so much faster than you can download in the first place?(u=350-400kB/s versus d=250 kB/s)It's unusual for upload to equal download...and unheard of for upload to be faster.

jewelisheaven Posted June 17, 2008 Report Share Posted June 17, 2008 Symmetric fiber ?Limiting download shouldn't affect upload... What happens when you use the Scheduler in Seed-Only mode?If you're trying to limit download, limit connections per torrent MORE. It will divide (theoretical download / connections) to give a set rate of download for the peers.. which COULD be what triggers uT into thinking it should slow uploading.

Skychaser Posted June 18, 2008 Author Report Share Posted June 18, 2008 Thanks jewelisheaven, I'll give your suggestion a try. And yep, symmetric fiber it is. Download is capped pretty hard on 2mbit, upload not so much, highest I got was 470kB/s. Link to comment Share on other sites More sharing options...
Ultima Posted June 18, 2008 Report Share Posted June 18, 2008 Known issue. µTorrent has no way to control its download rates accurately because it has no direct way to control how fast other peers decide to upload to it. At best, it can choke other peers in an attempt to get them to reciprocate less (which is what's probably happening here). Link to comment Share on other sites More sharing options...
Switeck Posted June 18, 2008 Report Share Posted June 18, 2008 Lowering how many connections per torrent and connections max you allow should reduce the download overloads slightly. Even the upload slots per torrent can affect this. Link to comment Share on other sites More sharing options...
