A resource profile will figure out how many resources your game will take, and in turn, how much compute power a server needs to reserve to run your game.
Once your game is profiled, the server will use this to calculate what is required by its pre-loading algorithm.
A resource profile is your vCPU × RAM memory
Resource profile focuses mainly VCPU and the memory required for the game server to run. Better optimised your game, the cheaper the price of running your servers.
