What Assumptions Make: Filesystem I/O from a database perspective

Selena Deckelmann, profile picture
Selena Deckelmann

The document discusses the performance testing of various filesystems for PostgreSQL, focusing on hardware and software configurations. It shares findings regarding throughput, RAID configurations, and common assumptions about filesystem performance, questioning traditional beliefs like the superiority of non-journaling filesystems. The presentation aims to aid performance tuning and underlines the need for periodic testing with specific setups, while emphasizing that results can vary significantly based on the configurations used.
