Performance issues with SWAG reverse proxy

Hello everyone,

I’m having an issue with the SWAG container regarding its performance, more specificaly the bandwidth and the reverse proxy on my Plex container.

I seemed to be having playback issues on my plex server when I was on my data but no issue when on the wifi, so I installed Librespeed to test the performance of the reverse proxy.

When accessing Librespeed directly through the open port on the container, I get the results on the left
But when I access through SWAG reverse proxy, I get the results on the right.

As you can see, the bandwidth is significantly worse when routing through SWAG.
Does anyone have any idea on how to resolve this issue, or if it can be resolved at all?
This isn’t an issue for radarr/sonarr but it is for Plex.

Everything is installed on a Raspberry Pi 4 8Gb with a docker compose to manage all containers.
