is it normal that a wireguard docker container provides "low" networkspeed for connecting containers?

I'm using a wireguard docker container to provide vpn connection to a qbittorrent container. When I compare it to wireguard on linux and the qbittorrent application, the same torrent is way slower. My server gets 2Mbit/s and my computer 15Mbit/s The 15Mbit/s is where my internet connection caps, while downloading that fast I can't watch YT videos. They both are in the same network using the same vpn provider and same endpoint.

for qbittorrent docker-compose I use network_mode: service:wireguard

  • Can you please share your compose file?

    I personally use a separate container instead of another service, not sure what difference it makes

    network_mode: "container:wireguard"

    Using the lscr.io/linuxserver/wireguard:latest image btw

    • services:
        wireguard:

      • I would try it with the SYS_MODULE and /lib/modules lines uncommented. That's how I have my container and it seems to perform just fine.
