Sudden slow upload speed
« on: February 13, 2018, 05:43:02 PM »
Hello.

I got qBittorrent a few days ago and everything was fine - I got nice dl/ul speeds, but yesterday overnight my upload speeds went almost to nothing.

Anyone knows why this could happen?

Thanks.

1.Torrent conditions may have changed?  (Fewer peers, trackers banned qBT, etc...)

2.ISP issues? (ISP now blocking/throttling torrents, outages and speed problems at ISP level)

3.Something wrong with your computer? (antivirus/antimalware/firewall in "learning mode" declared qBT's traffic a DDoS attack and started blocking/throttling it)

4.Bugs in qBT...there's a few concerning slow speeds:
https://github.com/qbittorrent/qBittorrent/issues/7155
https://github.com/qbittorrent/qBittorrent/issues/7822
https://github.com/qbittorrent/qBittorrent/issues/7954
https://github.com/qbittorrent/qBittorrent/issues/8027
(not a thorough search on my part)

Hmm it seems to depend on the torrent. Some have high upload speeds, while others not.

Depends on the peers and the amount of seeders available. Im always maxing my uploadspeed on private tracker but not always on public ones.

And of course maybe the points that Switeck mentioned.

My question is if it is within reason. I seed hundreds of popular linux ISOs on a dedicated fiber connection with SSDs and sometimes I see the upload drop as low as 30KiB/s for hours at a time. The monthly average is a pretty constant 15Mb/s, but at any given time it can be anywhere from 30KiB/s to 15MiB/s
