Describe the Bug

After upgrading to 1.12.0, I rolled back to 1.11.1 today on both my LAN Pangolin instance + my VPS instance with Gerbil/Newt connected to my Homelab. I'm using Traefik 3.5.4 on both. Tried also the new 1.12.1 update, but it's the same. Migration throws no error in logs.

Something is really off with 1.12.0 (at least both of my instances). The loading times of webpages (even in my LAN locally) multiplied by min. 5 times. After rollback, everything is blazing fast again.

Comparison with the exact same Service (Emby) using Pangolin/Traefik locally as my LAN Reverse Proxy without Gerbil/Newt over Gigabit:

1.12.0/1.12.1

1.11.1

Some of the same assets load up to 10 times slower than with 1.11.1. I've sorted the elements by loading time. In 1.11.1, the slowest element (the backdrop) is 300ms, in 1.12.0/1.12.1 it's 4 seconds. Man, you feel that when opening a webpage... and it's reproduceable. Tried to migrate 3 times from my 1.11.1 backup to 1.12.0 and then to 1.12.1, but it's the same everytime. 1.12.0/1.12.1=slow, back to 1.11.1=fast.

Environment

OS Type & Version: LAN Instance: Debian 12 / VPS Instance: Ubuntu 24.04
Pangolin Version: 0.12.0/0.12.1 (tried both)
Gerbil Version: 1.2.2
Badger Version: 1.2.1
Traefik Version: 3.5.4
Newt Version: 1.6.0
Olm Version: not used

LAN Instance just uses Pangolin+Traefik/Badger
VPS instance uses Pangolin+Gerbil+Traefik/Badger connected to 3 Newt in my Home LAN

To Reproduce

Open served ressource with 1.11.1 -> fast load times
Update to 1.12.0/1.12.1 -> long load time/laggy behaviour of ressource
Downgrade to 1.11.1 -> fast load times again

Expected Behavior

Update to 1.12.0/1.12.1 -> page load times are as fast as in 1.11.1
