# Set Up PgBouncer – PostgreSQL Connection Pooling on VPS

PgBouncer on VPS/root server: install, pool_mode, max_connections, Docker & systemd – make PostgreSQL 10× more efficient for web apps.

**Quick answer:** **PgBouncer** recycles PostgreSQL connections – instead of 500 connections only 20 real ones. Install between app and DB on your VPS.
