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. -- Kind regards, Antonio Rodriges -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
