The performance intensive parts of GitLab are written in Go, for example https://gitlab.com/gitlab-org/gitlab-workhorse/ https://gitlab.com/gitlab-org/gitlab-workhorse/ We're working on moving the git commands to https://gitlab.com/gitlab-org/gitaly/ https://gitlab.com/gitlab-org/gitaly/ this will help to improve cloning speeds.
