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?
You should be able to rebuild offline if the minimal change set is self contained enough, as in purely local. Did you update any other inputs? I guess you could be missing some kind of extra TLS or CA store dependency for adding custom CAs, but that doesn't seem likely for regular NixOS install. I use flakes instead of channels, so I wouldn't know what else may be blocked you. A stdout log may showcase your error more clearly.
I think you may need a successful switch to actually apply the addition of the proxy CA to your root CA store before attempting any other changes that could require reaching out across the network. At least that was the order of operations I had to follow to remove an offline remote cache before attempting any package updates.
Compiling the Linux kernel from scratch takes over an hour on this laptop. Given I'm tracking the unstable channel on a rolling distro means doing that several times a week. Ain't nobody got time for that. Or at least I don't...
I don't have resources to locally build an optimized kennel for every update for each of my systems, thus my interests in keeping with a community cache.
I didn't do much here, just swapped the kernel via config and ran some benchmarks. I posted as I was more curious to hear of what engineering trade offs may be at play, and what experience folks have had in daily driving CatchyOS's kernel patch sets.
I wasn't sure if these results were specific to my older hardware, or more generalizable to newer systems.
Check out the nix config repo from Unmoved Centre:
Hello Patrick! Thanks for the writeup; gradually incorporating it into my config.
BTW, I recall reading a PR you started on fixing the fallback from failing substituters? This may be of interest to you:
Only not by itself, no? Couldn't it be combined with any of those X11 server apps for hosting a display socket over the local loop back?
Still seems a little too idealistic, not sure how this would really shake down with more complex build systems or multilingual projects.
In addition to LoFi that others have recommended, I'd also suggest Chillstep. Chillstep is mellow, rhythmic, but without all the artificial scratchs and pops common in LoFi.
This is a playlist I tried to replicate from memory of the playlists I loved to listen to back before Google bought and closed down Songza, a curated music streaming platform:
BTW, if anyone could provide a better genre classification of this playlist, or similar albums/artists, I'd be grateful! I had to piece this together from sampling song radio suggestions and auditory recall, as I can't recall names, nor bothered to make note of them when auto playing from Songza back in the day.
There have been an influx of them in my RSS feeds, I wonder if there's been a You Tube or Tick Tock video that went viral about Nix some time earlier.
