Show HN: PostgreSQL performance and cost across 23 EC2 instance types
Summary
This post sizes a PostgreSQL server on AWS by benchmarking 23 EC2 instance types across different disks to meet a target throughput of 33,000 RPS. It shows the cheapest configuration that clears the target and highlights the best RPS per dollar, with Arm-based Graviton often providing favorable headroom. The data is presented in a sortable table with per-instance performance metrics.
