A benchmark comparing the performance of AWS RDS, self-hosted PostgreSQL on Hetzner, and Hostim managed Postgres for a small production setup (2 vCPU / 4 GB RAM) in central-Europe using PostgreSQL 16.
This comparison can help organizations make informed decisions about their database hosting needs, potentially leading to cost savings and improved performance.
- Hostim had the fastest writes, about 2.5× the write throughput of AWS RDS and 2.1× a default self-hosted Postgres on Hetzner.
- Hetzner had the fastest reads due to raw per-core CPU speed.
- AWS RDS was slowest or near-slowest on both write and read operations.
Quality:
The article provides detailed, reproducible benchmarks and comparisons.
