GitLab struggling when hosting a very large repo
We have old repos hosted on cgit which are themselves an export generated by git svn. These repos contain the whole of Arch Linux packaging history and are really large. They have more than one million commits amongst them with many millions of objects. We wanted to migrate these repos to GitLab. After importing, our GitLab became really slow and unresponsive. The machine's CPU was more or less constantly at 100% (8 cores, 32GiB memory). I didn't really find any way to tweak GitLab to perform better for our use case so we had to drop this experiment and uploaded the repos to GitHub instead.
We use GitLab Ultimate with the official Docker image.
We have opted to instead upload our packages to GitHub as we urgently needed a solution. The repos are now here:
