Tangential, but... I was so excited by their frontend, which was slowly adopting web components, until after acquisition by Microsoft they started rewriting it in React.
(Design is still very solid though!)
I can't say that I'm having issues with the performance either. I work with large PRs too (Especially if there's vendored dependencies) but I never ran into a show stopping performance issue that would make it "useless".
I used to run a GitLab instance for my own needs, however keeping up with the updates (especially across major versions) proved to be a bit too much and it was quite resource hungry.
My personal stack right now is Gitea + Drone CI + Nexus, though I might move over to Woodpecker CI in the future and also maybe look for alternatives to Nexus (it's also quite heavyweight and annoying to admin).
At this point Gitlab is just there because being even a small X% of a huge million/billion dollar market is good enough as a company even if the product is almost unusable.

I am not sure about tangled.sh, I might ask them in their discord about this now y'know.
