Postgres isn't slow, your storage is
A recent discussion on Hacker News argues that PostgreSQL’s perceived slowness often stems from the underlying storage subsystem rather than the database engine itself. Factors such as slow disks, inadequate I/O throughput, and misconfigured RAID can create bottlenecks, while proper SSDs, tuning, and monitoring can reveal PostgreSQL’s strong performance capabilities. Additionally, ensuring configuration, indexing strategies, and separating compute from storage during benchmarks helps avoid results.
