By real pagination i mean something like this when in page 3:

<<Previous 1 | 2 | {3} | 4 | 5 |...| 15 | Next>>

By Next and Previous buttons i mean something like this when in page 3:

<<previous Next>>

Performance wise im sure the Previous and Next Buttons are better since unlike the real pagination it doesn't require over-querying the database. By over-querying the database i mean getting more information from the database than what you will need to display on the page.

My theory is that the Previous and Next Buttons can drastically increase a site performance as it only requires the exact information you will need to display on a page, please correct me if im wrong on this.

so,

do users really have preference when it comes to this two options?

is it just a Developer preference and its convenience?

Which one do you prefer? why?

*Note: Previous and Next Buttons are usually labeled Newer and older.
