How much RAM do I need?

Hey! So I’m running a game server and I’m looking to use GitLab community edition to keep track of changes and work with my developers. Now I have a VPS of 8 GB ram, but there is also a gameserver running on it. I’m not looking to use more then 5 users and there will be one repo only which includes all the files of the gameserver.

I was hoping for this that I did not need more then 2 GB ram since I saw 4 GB will hardly run 100 users.

not an expert, but reading the docs at the moment…:
