CPU performance

Dear colleagues, please help me to find some sort of guide on how to work with CPU load (apart from CPU profiling). I am interested in such particularities as huge performance difference between using Static NavMesh and Dynamic Navmesh, processor load during dynamic changes of objects’ location. I am also very concerned how to manage processes in Unreal Engine (for example in many games when you’re minimizing it, it decreases the load (as far as I understand it happens because the number of ticks is being decreased, but unreal’s session is always actice and loads the processor)

Best regards, your friend, Alex.
