Odoo Performance Slow? Optimize Now!

Odoo Performance Slow? Optimize Now!

Have you ever clicked a button in Odoo and waited… and waited… and waited?

Imagine this: You’re processing payroll, and suddenly Odoo freezes. Your team stares at the spinning wheel, productivity drops, and frustration grows. Slow Odoo performance isn’t just annoying—it costs time and money.

The good news? Most Odoo slowdowns are fixable. Often, the culprit is inefficient database queries. Let’s dive into how you can diagnose and speed up your Odoo instance—starting today.

🔍 Why Is Odoo Slow? Common Culprits

Odoo relies heavily on PostgreSQL, and database bottlenecks are a leading cause of lag. Here’s what might be happening:

  • Unoptimized queries – Some searches or reports pull too much data inefficiently.
  • Missing indexes – Frequently searched fields without indexes slow down lookups.
  • Bloated logs/attachments – Over time, logs and files eat up space and slow backups.
  • Underpowered server – Odoo needs enough RAM, CPU, and fast storage (especially for large databases).

⚡ Step 1: Find Slow Queries (Enable Debug Logging)

To identify problematic queries, enable Odoo’s debug mode:

  1. Edit your Odoo config file (e.g., odoo.conf).
  2. Add or update this line:
    log_level = debug
  3. Restart Odoo.

Now, check Odoo logs (/var/log/odoo/odoo-server.log). Look for slow queries (e.g., those taking >500ms). Example log entry: 

DEBUG ... QUERY TIME: 1.2s  
SELECT ... FROM res_partner WHERE ...

💡 Pro Tip: Use grep to filter logs: 

grep "QUERY TIME" /var/log/odoo/odoo-server.log

📊 Step 2: Analyze with pgBadger (PostgreSQL Wizardry)

For deeper insights, use pgBadger, a tool that visualizes PostgreSQL logs:

  1. Install pgBadger:
    sudo apt-get install pgbadger  # Debian/Ubuntu
  2. Parse your PostgreSQL logs:
    pgbadger /var/log/postgresql/postgresql-*.log -o report.html
  3. Open report.html in a browser.

What to look for:

  • Top slowest queries
  • Frequent queries (could benefit from caching)
  • Missing indexes (flagged as sequential scans)

🛠️ Step 3: Optimize Your Database

A. Add Indexes to Speed Up Searches

Indexes help PostgreSQL find data faster. For example, if res.partner searches on email are slow: 

CREATE INDEX res_partner_email_idx ON res_partner (email);

Common fields to index:

  • name (frequently searched)
  • Foreign keys (e.g., partner_id, user_id)
  • Date fields (e.g., create_date for filtering)

⚠️ Caution: Don’t over-index! Too many indexes slow down writes.

B. Clean Up Your Database

  • Archive old data: Move inactive records (e.g., old invoices) to separate tables.
  • Purge logs: Clear ir.logging and ir.attachment if bloated.
  • Vacuum PostgreSQL: Run VACUUM FULL ANALYZE; during low-traffic hours.

C. Tune PostgreSQL Settings

Adjust postgresql.conf for better performance: 

shared_buffers = 25% of RAM  
effective_cache_size = 50% of RAM  
work_mem = 4MB (increase for complex queries)

🚀 Bonus: Quick Wins for Faster Odoo

  • Enable pg_prewarm: Cache frequently used tables in RAM.
  • Use a CDN for static files – Speeds up page loads globally.
  • Upgrade hardware – SSDs and more RAM make a huge difference.
  • Check cron jobs – Long-running scheduled actions can hog resources.
