Hi Juan,
I think there is no right/wrong number, as Kublin added on this thread
there are several approaches to address this issue.

My 2 cents on this is that a change should be based on a given workload
profile. Any given solution would suits specific workload and hurt
another, as long as we are not sure what is the common workload our
users use I would make any change configurable and write a
recommendation on how to configure it.
For writing such document one should characterized few typical usages of
the system and test what is the preferred configuration for them.
