Hey,

The following bug concerns µtorrent, aswell as Bittorrent.

I'm on a 50MBs line, with my real download being 46MBs (5,7mbs) and upload maxing 8MBs (1,2mbs).

When downloading a torrent with unlimited uplaod, the download speed is almost halfed, when I limit the upload by half, it boosts the download speed, like seen in the image below.

This is reproducable at any time.

Although not a big problem besides me only being a 50% good person if I want 100% of my download speed, it creates the need to again select unlimited upload speed once the download is complete and it starts seeding. If I forget to do this, im again only a 50% good person, although I would like to be a 100% good person :]

This seems to be overhead related aka, maxing out upload prohibits the announces of being send at full speed? Encryption on or off does not change the problem.

No other Internet hungry stuff is present.

Preferences - bandwidth.

Set the regular max upload rate to your 50% speed and enable the "Alternate upload rate when not downloading" option set to 0.

As for the overhead, there's not a lot you're going to be able to do, except possibly set a limit close to your line's rated upload and have the overhead included in your rate limit

This is no bug. If you unlimit your uploadspeed, then it will happen, that all your available upstream is used for sending data to other peers. But this means, that almost no upstream can be used for communication with other peers while upstreaming to the fullest. But torrent needs this communication to request parts for you to download. So set your upload toaybe 70-80% of your possible upspeed. Then there is some bandwidth left for requests and communication. Be warned, this is a scenario in which nobody and no other process uses your internetconnection at home ;)
