I ended up upgrading (used a new sdcard) to bookworm, I used the Ubuntu PPA to install deluge. Info: Client: 2.1.1 Server: 2.1.1 libtorrent: 2.0.8.0 With the same Ubuntu ISO I am able to max out my internet connection. I can't confirm which change made the difference as I'm now using a newer version...

I will look into these settings when I have some time. I may also try the new bookworm debian which should allow me to install the latest Deluge version.

Hi cegueira, I would advice you to scp or move a large file from the raspberry pi to your computer so you are sure that it is the fault of Deluge. Or else you will just be wasting your time looking at the wrong place as the root cause. The should be the first step in solving computer/software issue...

I think it must have something to do with deluge or this libtorrent version, as using qbittorrent on the same pi, saving to the same location (USB 3 HDD), with the same torrent yields 4x speeds, maxing out my internet connection. Incidentally iperf3 test (LAN), between two raspberry pis (with a swit...

I've just upgraded my internet connection from 80/20 to 500/80 (Mbps). I'm unable to get much past 10MBps downloading in deluge. In qbittorrent on the same system it gets to 49MBps. I am testing with a Ubuntu ISO, and leaving the torrent active for >2 minutes, a separate port has been opened for eac...

Hi,

I've solved the issue, don't know if it was due to the change of Debian versions but just in case it comes up for anyone else:
edit: /etc/systemd/resolved.conf
and set: Cache=no

Cheers.

I have previously been running Deluge 1.3.12 successfully on an old Pi2. I have got a Pi 3B+, and if I make a change to the hosts file Deluge only acknowledges this change if I restart the daemon, pinging from console is affected by the changes to the hosts file.

Does deluge cache DNS queries?
