The goal of the project is to have the cache be directly readable by nix without having to rely on the server, because high-available s3 storage providers are a commodity - having to set up postgres cluster on the other hand is not so trivial. Also I still see reports for attic about having very slow uploads: [Celler: An Attic Fork - #19 by greg-hellings](https://discourse.nixos.org/t/celler-an-attic-fork/77265/19) This also matches my own experience from when I tested it. I rather take performance/high-availability/stability over storage space. S3 storage is dirt cheap for projects I have used so far, given you have a garbage collection to be able to garbage collect eventually. Downloads speeds of 10-20mb/s don’t sound great. With cloudflare r2 I can get easily gigabit speed and more.
