One of our customer is planning to implement RH GitOps in their production env and looking for any Best-Practices/Guidelines for RH GitOps operator optimum performance as it comes with default values for CPU and memory for all parts but there is no documentation on for which setup( Regarding to High availability/Load/Application No, etc ) these are valid?

The customer's main asks are:

• There should be documentation created or somewhere it should be mentioned that how much application and load can be handled via default or any other configurations.
• Pre test should be measured regarding diff memory/CPU parameters so it's easy to set them without wasting more resources.
• What resources can be changed and what not must be mentioned somewhere so the customer has to not open a ticket for simple asks.
