+Database configuration
+======================
+CPS uses PostgreSQL database. As per the `PostgreSQL documentation on resource consumption
+<https://www.postgresql.org/docs/current/runtime-config-resource.html#GUC-SHARED-BUFFERS>`_, the *shared_buffers*
+parameter should be set between 25% and 40% of total memory. It has a default value of 128 megabytes, so this should be
+set appropriately. For example, given a database with 2GB of memory, 512MB is a recommended value.
