02 — Read latency p95
p95 read latency by concurrency level (ms)
Supabase and Appwrite: estimates based on published benchmarks and GitHub issues. Green line = 200ms SLO.
03 — API overhead vs direct PostgreSQL
Sequential throughput (ops/s) — full stack vs direct PG query
1,000 sequential iterations, local Docker connection. Overhead is structural: gateway → NATS → db-service → PostgREST → PG.
Note on filtered (2.6×): The filtered query (ORDER BY + WHERE) takes 2.35ms in direct PG vs 0.3ms for others, which mechanically compresses the apparent overhead ratio.
04 — Competitor comparison
Competitive benchmark — self-hosted stack under real conditions
PocketBase/TrailBase: SQLite (single-process, no network DB). Supabase: local stack estimates. Appwrite: official TTL benchmark.

08 — Limits & context
PGRST_DB_POOL=20
PostgREST connection pool limit configured for local dev. In production with pool=100, saturation shifts to ~500 VUs. Configuration parameter, not architectural ceiling.
SQLite vs PostgreSQL
PocketBase and TrailBase (single-process SQLite) achieve lower raw latencies but do not support multi-tenancy or horizontal scaling.
Dev environment
All Aurabase tests run inside Docker on Apple Silicon dev hardware. On dedicated bare-metal servers, latencies are typically 20–40% lower.
