By the end, you'll have a working mental model — backed by real numbers — for choosing between PgBouncer (transaction mode), Supabase's built-in Supavisor pooler, and Neon's serverless proxy. You'll also get a reusable benchmark harness you can adapt to your own traffic patterns. ## Prerequisites - A PostgreSQL 15+ instance (local or cloud) - Node.js 18+ or a C
