Amazon RDS for PostgreSQL now supports Linux kernel huge pages for increased database scalability. The use of huge pages results in smaller page tables and less CPU time spent on memory management, increasing the performance of large database instances. Amazon RDS for PostgreSQL supports multiple page sizes for PostgreSQL versions 9.4.11 and later, 9.5.6 and later, and 9.6.2 and later.

Huge pages are off by default. To enable them, set the huge_pages PostgreSQL runtime configuration parameter to on. Complete instructions are available in the RDS for PostgreSQL documentation.

Amazon RDS for PostgreSQL makes it easy to set up, operate, and scale PostgreSQL deployments in the cloud. See Amazon RDS for PostgreSQL Pricing for regional availability.
