Not OP but I have a number of gitlab instances:

For 5 users we use 18G/4vCPU. For 20 users we use 32G/8vCPU

I keep asking to lower the footprint but the gitlab is the very definition of feature creep. And that comes at the cost of optimisation.

We support 30 developers on 10gb ram and 4 cores. That said, we are probably a year and a half behind version wise and only use it for its SCM capabilities.
