As for what each query should do.. I'm not sure that this question has
an answer. It would relate entirely to your database schema and how you
write your queries, and I am not aware of any benchmarks or metrics for
this kind of information.
On a side note, there's plenty of resources as to what each tuning
parameter does and what the optimals are for many situations.
