I’ve observed some notable improvements when benchmarking with the CachyOS kernel on NixOS via Chaotic’s Nyx using moderately old hardware:

Haven’t yet tried replicating the same comparison on newer hardware, but would be interested to see what others have tested. Any observations?

Looks like they introduce the use Traefik with NixOS here:

How does Traefik compare to a reverse proxy like Caddy?

I’m not the original author, even with the YouTube title being as is, but what do you mean? Perhaps relying that the desired services exist as nix packages, or that nix packages have desired defaults or exposes desired config parameters?

There are two other nix media server config projects I can think of, but I think this approach mostly facilitates the install, but not the entire initial config setup, given that a lot of the stack’s internal state is captured in databases rather than text config files. So simplifying the backup and restoration of such databases seems the next best thing to persist your stack configs with nix.
