All;
I'm working with a client running PostgreSQL on a Fusion-IO drive.
They have a PostgreSQL setup guide from Fusion recommending the
following settings:
effective_io_concurrency=0
bgwriter_lru_maxpages=0
random_page_cost=0.1
sequential_page_cost=0.1
These seem odd to me, effectively turning the background writer off,
plus setting both random_page_cost and sequential_page_cost to the same
(very low) value...
Thoughts?
Thanks in advance
