@null0x0 I haven't actually looked into it. GitLab is definitely heavy on resources, but it is also rather feature-rich, much more than the alternatives (for example, Gitea has no CI/CD, so you have to rely on Jenkins while GitLab is an all-in-one package, easier to manage).

For now, since the GitLab server is only used primarily by me, I have no performance issues there or anywhere else.
