Identifying the Bottlenecks

Learn about the basics of tuning the parameters in a PostgreSQL database to optimize performance.

Different types of bottlenecks

Identifying bottlenecks in a PostgreSQL database is an important step in improving performance and ensuring efficient and reliable operation. There are several areas where bottlenecks can occur, including disk I/O, CPU utilization, memory usage, and network activity.

Disk I/O

Disk I/O is a common bottleneck in PostgreSQL databases. If disk I/O is slow, it can take a long time for the database to read and write data, leading to slow query performance and increased latency. We can use the pg_statio_user_tables view to monitor disk I/O activity and identify any tables or indexes that may be causing performance issues.
