02 — Read latency p95
p95 read latency by concurrency level (ms)
Supabase en Appwrite: schattingen op basis van gepubliceerde benchmarks en GitHub-problemen. Groene lijn = 200 ms SLO.
03 — API overhead vs direct PostgreSQL
Sequential throughput (ops/s) — full stack vs direct PG query
1.000 opeenvolgende iteraties, lokale Docker-verbinding. Overhead is structureel: gateway → NATS → db-service → PostgREST → PG.
Opmerking over gefilterd (2,6×): De gefilterde query (ORDER BY + WHERE) duurt 2,35 ms bij directe PG versus 0,3 ms voor andere, waardoor de schijnbare overheadratio mechanisch wordt gecomprimeerd.
04 — Competitor comparison
Competitive benchmark — self-hosted stack under real conditions
PocketBase/TrailBase: SQLite (enkel proces, geen netwerk-DB). Supabase: lokale stapelschattingen. Appwrite: officiële 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.
Tests uitgevoerd op 29 mei 2026 · Stack: Rust 1.87 · PostgreSQL 16 · k6 v2.0 · Criterion.rs 0.5 · Concurrentiegegevens afkomstig van officieel gepubliceerde benchmarks.
