qBittorrent official forums

Hello!
I have QBittorrent v 4.1.4 and fiber internet.The download speed is as it should,but the upload speed is very low.
Are there some options so the upload speed can increase?
I have Windows 10 64 bit.The port is open and working ok through my router also.
Any help is appreciated.
Thanks in advance !

The slow upload speed can be due to private trackers with lots of seeds per peer, so that even if qBT connects to a peer it's "out-uploaded" by all the other seeds combined. A lone peer under those circumstances is often overloaded and cannot download very much from any individual seed.

On public torrents, many peers may have low-speed internet connections (even dial-up still!) and/or be throttled by their ISP. They might also have set their BitTorrent client such that it can't download quickly because others sharing the same internet connection have threatened them with harm if they keep hogging it all.

The questions I'd have to ask to determine the cause/s are:

1.Are you downloading torrents at the same time trying to upload? (download-induced overloads can murder upload speeds)

2.Are you testing using a single torrent that has few seeds but many peers? ...with other torrents either stopped or at least no connected peers+seeds?

3.Are you using a Proxy or VPN? (These sometimes silently change their policies on BitTorrent use, causing 'instant' speed losses. Their transit provider may throttle BitTorrent traffic even if they don't!)

4.What are your... qBitTorrent's general settings for max connections and max upload slots -- both globally and per torrent -- as well as other settings such as whether uTP is allowed or forced, half open connection max (>10 can cause overloads on poor networking equipment+software) all of which may have a huge influence on how well it can DL and UL.

5.Lastly, how fast is your download and upload supposed to be? What's the results you get when running speed tests? (include a link to the results if that's easy to do...)
