Technical Overview
Engineering breakdown of Scaling PostgreSQL Connection Pooling with PgBouncer (4106). Bare-metal hardware performance requires isolated kernel parameters, tuned max_connections, and precise PgBouncer pool modes (session, transaction, statement). We explore connection lifecycle, memory overhead per backend, and the impact of default_pool_size vs max_client_conn on throughput under high concurrency.
Key Metrics
- Connection acquisition latency (p50/p99)
- Transaction throughput (TPS)
- Backend memory footprint
- PgBouncer CPU utilization
Benchmarks run on 32‑core AMD EPYC, 256 GiB RAM, NVMe storage, PostgreSQL 16, PgBouncer 1.22.
