There already is https://github.com/fosrl/pangolin/issues/707 and https://github.com/fosrl/pangolin/issues/924, but I do not even reach 100Mbits (and changing the MTU did not help), and none of my servers show any CPU spikes.

I migrated from Cloudflare with NPM to Pangolin and have to say it works great up until this point. But now I wanted to download something from my Nextcloud, and instead of the expected 50MB/s (400Mbits/s), I only get about 1MB/s.

Both servers have enough upload and download speed, and it worked fine with NPM and Cloudflare. This is my first time using Traefik, so maybe I set something up wrong. But I only configured it in a very basic way with CrowdSec and the default non-managed Pangolin.

Is there anything I can try to increase speeds, because this is very slow and affects all subdomains.
