We can raise up checkpoints, at kernel-side which options do you suggest to tune for minimize disk writing?
We have a table, about 500Mb, that is updated and written every day.
When machines updates, table is truncated and then re-populated with pg_bulk.
But i think we strongly writes when importing new data tables..
Here is why we tought putting some tables into ramdrive...
Thank you,
