There are people at GitLab that know more, but my take is that it would make it more practical to run with 1GB. As listed in https://docs.gitlab.com/ce/install/requirements.html https://docs.gitlab.com/ce/install/requirements.html the minimum is 1GB "1GB RAM + 3GB of swap is the absolute minimum but we strongly advise against this amount of memory. See the unicorn worker section below for more advice." Most of the memory for the configuration of 4GB we recommend is to run extra unicorn workers https://docs.gitlab.com/ce/install/requirements.html#unicorn-workers https://docs.gitlab.com/ce/install/requirements.html#unicorn... You would save this memory because you can multithread one worker.
