✅ 1. Review Server Specifications:

Ensure the server meets the minimum recommended specs:

• CPU: 4 cores minimum (8+ preferred for heavy usage)
• RAM: 8GB+ recommended
• Disk: SSD with high IOPS
• PostgreSQL: At least v13 or higher

✅ 2. Check Custom Modules:

Outdated custom modules from older versions can:

• Slow down views and reports
• Break lazy loading
• Cause inefficient SQL queries

Use the Odoo Profiler (Developer Tools > Performance) to identify bottlenecks.

✅ 3. Enable and Tune Caching:

Use ir.config_parameter to enable:

• QWeb caching
• Asset bundling
• DB and HTTP caching

Activate --workers in production (for WSGI multiprocessing) instead of using --dev mode.

✅ 4. Optimize PostgreSQL Configuration:

Fine-tune PostgreSQL using:

• work_mem = 64MB
• shared_buffers = 25%-40% of RAM
• effective_cache_size = 70%-80% of RAM
• Install pg_stat_statements to monitor heavy queries
