ModX base resources consumption

Hi there, I need to prepare a resources consumption baseline for a migration we are doing for a client, I know that the application itself will consume resources based on what we developed, and I must do some load test to understand how our development behaves, but I need to present a baseline of how much (ram, DB, storage) will be consumed by a basic ModX installation, I have look into the docs and haven’t managed to find such information, any ideas where can I find this?
