GoKawiilBenchmark finds local NVMe outperforms gp3 EBS on 3.3B-row Postgres workload
At POSETTE 2026, Sai Srirampur presented a benchmark comparing a 3.3-billion-row PostgreSQL workload running on baseline gp3 EBS storage versus local NVMe storage. The talk argued that common scaling symptoms—slow ingestion, inconsistent read latency, autovacuum falling behind, and slower checkpoints—often trace back to storage performance rather than Postgres itself, and proposed architecture patterns for running Postgres on local NVMe in production.
