Increasing the number of database writers will increase your memory
consumption, but it should not be to large. Each writer is a slave to the
master writer and thus should consume no more that 1.7Mb. If Async io is an
option on your platform I would recommend it, because all multiple database
writers mimics is async io.
Each session is responsable for reading, thus increasing the number of database writers will not help read performance. To increase read performance for full table scans or fast index scans consider parallel query.
