Speed drops from 2MB/s to 40KB/s to ~0KB/s?
Posted: Wed Jul 20, 2022 5:40 pm
Hello!
Hope somebody could help me out:
Issue: Speed starts out fine at ~2MB/s. Then after a while (1-2 hours) speed drops to 40KB/s, and then later one it might drop even more. See attached pictures.
Info:
Internet: 500Mbit
VPN: Yes
Version: 4.2.5 (From Raspbian(Debian) Stable repo)
System: Raspberry Pi 4 8GB
Saving to external USB flash drive
I have testet that:
- if I restart the torrent client, speed increases again. But it seems like I have to kill the process in order to restart it.
- if I use another torrent client (transmission) these issues did not occur
- I have checked the execution log and starting qbittorrent from terminal without finding any substantial useful information. Anywhere else I could look?
- Mounting the external exfat drive with async does not make any difference, however I still think this might have to do with writing/reading to an external drive - but other bittorrent clients does not have this issue.
Any Idea what this could come from? IO issue? Connections issue?
EDIT:
Ok, this is rather interesting. After closing qbittorrent in the gui, I ran iotop, and it seems to be reading and writing? Why? See attached photo.
