Hello,
Does anyone know whether PostgreSQL uses DMA (Direct Memory Access) in
certain cases to improve networking IO performance?
I mean "simple" query is which doesn't require any CPU processing, for ex
SELECT column_a FROM table_b WHERE date = "2001-10-05"
I need this to devise the best logic for the system with PostgreSQL as
a layer. Certainly I could study PostgreSQL sources or test it with a
simple application but I hope PostgreSQL experts are aware of this
feature.
Thank you.
