Do torrents in uTorrent’s queue use bandwidth?

Garris Rago March 8, 2013

So basically I’ll have like 40 torrents open in uTorrent at once. I have it set so that only 2 are ever active, 1 downloading and 1 seeding. The rest are in the queue.

My internet has been slow lately, and a friend saw my uTorrent and said that even if they are in queue they are using up bandwidth, but I’m not so sure?

It’s uTorrent 3.3 (build 29126) 32-bit. Just realised it’s 32-bit on 64-bit OS but hey ho, it’s been working for ages!

    The torrents in que use Bandwith but at a minimul level , 2-3 Kbits each ,periodically to check the available connections and keep a placeholder for uploading-downlonding priorities . If in your settings have set a high value for connections per torrent the above number may spike. So if you have many queued torrents and a setting for a high number of connections per torrent , you may experience a small lag in your banwidth.

    I'm not sure how the queue of uTorrent works ~ if there are peers/seeders listed for the queued items they are "active" in a way and use some bandwidth. If there are no peers/seeders listed those queued downloads don't use bandwidth.
    Having that said neither one should have a noticeable impact on your connection. More likely the problem is with your bandwidth settings (connections per torrent, connections global, max. half-open).While Windows 7 doesn't have a limit for half-open TCP connection you can assume that somewhere around 100 it will start to cripple any other internet activity so you might want to keep this (advanced utorrent) setting under 5 (my suggestion would be 10-20). As for the active connections it really depends on all the stuff going on in your network. Basic broadband routers usually can't handle much more than 1500-2000 connections before they get slow and at some point overloaded. If you have other devices on your network you should limit the global connections to 1000 or better 500. With 2 active torrents the connection per torrent are then (obviously) 500 respectively 250.

      * was supposed to read (advanced utorrent) setting under 50...

    Bandwidth is total of upload and download usage
    To save bandwidth don't keep the torrent file seeding and paused.
    Limit the up speed of torrent file to few kbps to save bandwidth.

    You could set the download/upload speeds of those idle torrents.But again I would advise you not to open so many torrents at once. Simply download the one you require "right now".

    well, if the other torrents are on the queue but are stoped (select the line of the torrent and press the stop icon above) at the same time, then those are not consuming bandwidth, just those two you say are not stopped.

    Items that are queued still use a small amount of bandwidth by checking the network and noting who is seeding, what parts of the queued downloads are available, and tracking who wants a piece of any files you are currently seeding or downloading. You can get better performance by keeping the total number of files in uTorrent small (this includes both the files you have completed downloading which are currently seeding and the files you are downloading/wish to download).

    Of course torrents use bandwidth! To quote from uTorrent's page: "ĀµTorrent is instinctively smart. It auto-adjusts bandwidth usage based upon your network and the Internet. Use Skype, play games, stream video etc., all without interference."

    However, the question is _how much_ bandwidth they use. Overall, you can see your network traffic in the Task Manager (press Ctrl+Shift+Escape to bring it up, and click the "Networking" tab to see the overall figure. Beyond that, you can choose Options=>Preferences... and limit the upload and download speeds in the "Transfer Cap" and "Queuing" tabs respectively.
