🚨 Is your Odoo slow when there are many users?
If your Odoo instance:
becomes slow with few concurrent users
consumes a lot of RAM without using CPU
shows connection errors to PostgreSQL
"fixes" itself by restarting services
👉 The problem is almost never Odoo. It's the management of connections to PostgreSQL.
Y ahí es donde entra PgBouncer.
🎯 What you will learn in this guide
This course is not theoretical. It is based onreal production, common errors, and tested configurations.
You will learn to:
Understandwhy Odoo collapses without a pooler
Install and configurePgBouncer correctly for Odoo
UseSCRAM-SHA-256without breaking authentication
Calculate theideal pool_size
Avoid deadlocks, starvation, and timeouts
Monitor PgBouncer before the user notices the problem
Design asolid architecture Odoo + PgBouncer + PostgreSQL
🧠 Why Odoo needs PgBouncer
Odoo opensmany simultaneous connectionsto PostgreSQL.
PostgreSQLis not designedfor thousands of active connections.
Without PgBouncer:
Increasing max_connections only worsens the problem
Each connection consumes memory
Locks, latency, and timeouts appear
The system scales poorly
With PgBouncer:
Fewer real connections
Lower RAM usage
Better latency
Escalabilidad real
👤 ¿Para quién es este curso?
This content is for you if:
You manage Odoo in production
You have more than 20 concurrent users
You are a partner, sysadmin, or DevOps
You wantstable performance, not patches
❌ Not for test or demo installations.
