Slow speed on raspberry pi

[cegueira]

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 each client.

Anything I can try, I would like to keep Deluge as I like having the thin client.

Raspberry Pi info:
PRETTY_NAME="Raspbian GNU/Linux 11 (bullseye)"
NAME="Raspbian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye

Deluge Info:
Client: 2.0.3
Server: 2.0.5
libtorrent: 1.2.9.0

Hi,

I don't think Deluge is at fault with this. Before i bought my new SBC i had the same experience with Raspberry Pi 4 (in my case). I could ONLY reach speeds up to around 50-60 MB/s. And i am not talking about internet speeds but also network speeds. When trying to SCP a file or even more files i could not reach higher speeds. Tried SMB that was also slow. Usually using SCP you could reach the maximum when it comes to speed.

Back then i was using M.2 NGFF SATA over USB 3.0 (which is still 5 Gbit and my network was 1 Gbit), but i simply could not reach higher speeds. With my current SBC (Radxa Rock 5B) i can reach the maximum speed (which is 1 Gbit, as my network is the bottleneck. It is only 1 Gbit network. Currently trying to upgrade everying to 10 Gbit).

But yeah it is sad..but it is what it is. Maybe open for a Radxa Rock 5B?..i promise you i am not getting any commission . It is just a very good product. (up to 8 cores, 16 GB RAM and M.2 NVME slot)

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 switch and an AP between them):

Try updating to a 2.x version of libtorrent or more up to date version of 1.2.x.

you can pypi or @mhertz can link you to his build of the latest

[mhertz]

Sorry don't know anything about raspbian i'm affraid, or arm in general or however called, and not sure if even available on pypi honestly(the right type arm also), but could try see yourself, or check with if 'pip3 install libtorrent' succeds.

[cegueira]

pip3 install libtorrent:
ERROR: Could not find a version that satisfies the requirement libtorrent (from versions: none)
ERROR: No matching distribution found for libtorrent

We may be able to rule out the libtorrent version, below is the qbittorrent software info:
Qt: 5.15.1
Libtorrent:1.2.9.0
Boost: 1.71.0
OpenSSL: 1.1.1w
zlib: 1.2.11

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 issues to see the root cause and from there go to the next step.

I don't really see the point in doing this as it takes me 3 minutes to download the iso on qbittorrent and 11 mins to download the same iso with deluge.

ooh wait i think i have missed your other reply.

I do have noticed some of the settings in Deluge. One for example is Peer TOS Byte but also Hide Client Identity.

The Peer TOS Byte is set to 0x08
Hide Client Identity[ is unchecked.

Besides these two settings i have noticed that if you are downloading from another client that is also using like Deluge it goes much faster than if it is using lets say transmission.

Besides these things i would also suggest to start using the latest version of Deluge to see if the problem has been solved, because for now i see no other reason if other clients to have a very high speed.

[ambipro]

I would think that most of the speed issues would be the same across clients if using the same libtorrent library...

I'm not really sure where the actual writing comes from, whether Deluge does the IO but I'd think now based on ltconfig settings for write/read and IO threads. You might try and adjust those, aio_threads and others (google libtorrent settings for this)

Situation sucks, I had IO problems before but it ended up being the hardware.
