Not necessarily. Only if you run queries that access more than 256M of the db 
file AND there is no contention for memory resources.

Why is the PSS of your process such a concern?

Betreff: Re: [sqlite] [EXTERNAL] Does mmap increase PSS?

Thanks a lot, Hick.
So, if
- mmap_size=256M
- run only one copy of my program (has no other process to split PSS)
- have a large enough amount of main memory (bigger than 256M)
- a big db file (bigger than 256M)
Then the PSS of my program will be about 256M.

Is that correct?
