qBittorrent official forums

Hello, I'm new and I would like how to configure qbit for best performance, thank's. Sorry I'm french.

qBitTorrent's settings depends mainly on the sustainable UPLOAD speed of your line, how many torrents you try to seed+download at once, and even the type of trackers used or whether your connection is badly/hopelessly firewalled.

ok, so is there anyone can help and show me how to do it, thank's.

Not without more information, otherwise I cannot explain why I make the choices I do.
One size does not fit all!
