Like any database, PostgreSQL is very dependent on the system's IO. In many situation's a poor performing database is directly related to how PostgreSQL is reading or writing to the disk and using memory. A key factor in improving performance is understanding how PostgreSQL is interacting with these resources.

In this talk I will discuss the interactions between shared buffers, OS buffers, WAL buffers, temporary files, kernel tuning parameters and more.
