> The Ruby on Rails tax.

Yeah, from my experience administering a pretty small self-hosted instance, I think it's got to be this. Every single admin action you try to take on the backend is SLOWWWWW. Restarting the services takes a few minutes. Just to bring up an admin console on the server in a CLI takes well over a minute, which indicates a tremendous amount of overhead purely on the ruby side.

There's just something fundamentally slow about how it's all put together. I wouldn't blame the language or tech stack, exactly - but perhaps Ruby on Rails is not a great fit, anymore, for a fully featured forge of this scale?
