nix-tree VS cachix

Excellent recommendation!

For reference: https://github.com/utdemir/nix-tree

Or, to test without installing:

$ nix-shell -p nix-tree

$ nix-tree

etc.

Anyway, excellent suggestion!

whose output is [here](https://www.wolframcloud.com/obj/c863257b-9c05-4bb3-8790-2caf2e230295); however, in classic nix fashion (where literally every dependency all the way down the stack is specified), this leads to a 22K line file, which isn't very useful. [nix-tree](https://github.com/utdemir/nix-tree) provides a more manageable way to explore dependencies interactively if you are looking for more detail.

I've been trying to gradually introduce Nix more into my development.[0]

One roadblock I haven't been able to overcome is integrating Nix in CI. In my case, I use CircleCI. I know there are Nix-centric CI platforms, but I've invested a lot into CircleCI and would like to stay.

The problem I hit is that if I switch from something like a sqlfluff Docker container to a Nix Docker container, my build job goes from 15s to 2m+ because now I have to download several gigs within the CI job and build my Nix environment from scratch.[1]

I tried Cachix, but the best I could get was bringing the job down to 55s (a roughly 3x performance penalty from an off-the-shelf Docker container).[2]

How does FlakeHub Cache's performance in CI compare to the default Nux cache or to Cachix?
