Benchmark compares PostgreSQL speed and cost on 23 AWS EC2 instance types

A recent analysis examined PostgreSQL performance across Amazon EC2 offerings. The benchmark covered twenty‑three different instance types. Metrics included query latency, throughput, and total cost of ownership. Results highlight trade‑offs between compute power and expense. Smaller instances showed lower cost but higher response times. Larger instances delivered faster queries at a premium price. The study provides guidance for developers choosing optimal hardware. Readers are encouraged to match workloads with appropriate instance classes.
