2M per BitMagnet instance. That’s about 18Gb in postgres. Not significant, but around where you start to think about query optimization.

BitMagnet isn’t a silver bullet. Its datastore use makes it rather unreliable past about 2M torrents mark.

I got my account closed with no reason a hair after 12 months. It was good while it lasted, and I have the backups outside of oracle’s cloud.

I wouldn’t specifically say nixOS is stable in the same sense debian is but yes, it can totally handle this use case. I mainly run k8s on it, but a few home machines run docker (or, rather, podman) containers.

A thing about nixOS is that quite often you won’t need containers at all and would be better off without them, managing your apps as part of the system state as a whole. I only do that because I can’t be bothered to properly switch to nixOS services for ELK (which is supported by nixOS).

It’s a very stable solution in general and usually ends with a configuration that either doesn’t apply at all or applies with no issues. Gitops included for pretty much free. It requires understanding nix, and it can be tricky, but not overly tricky.

All and all I haven’t had an Ubuntu in homelab for two years now and can’t be happier about that.
