Disk IOPS (Input/Output Operations Per Second) is a key metric for measuring the performance of any disk system. It represents the number of read and write operations that can be performed per second. For PostgreSQL, which relies heavily on disk access, understanding and optimizing disk IOPS is crucial for achieving optimal performance. Today I want to go through the key topics involved with IOPs - what is it, how does it impact Postgres, how to measure it, and what to change for better performance.
