also those min and max numbers and limit values he mentioned have no best value. just optimum value depending on use case and system specs. so this is not a tutorial.
at best it could be a reply to someone asking for a recommended config for his use case (or the op gives us that context). but i dont see anyone asking for that. without that , some explanations would save the day. but no. they are nowhere to be found either...

sorry.. way too much rant today..
