I use GitLab CE since 2012, and checking https://docs.gitea.io/en-us/comparison/ gitea vs gitlab the main difference is: "Low resource usage (RAM/CPU)"

I see why: Gitea is 75%-Golang, 13%-HandleBarsJs GitLab is 85%-Ruby 12%-HTML

Never have a problem with Gitlab, but is RUBY is slow and cpu demand

I will try it !
