✅ Root Cause:

• Each field loads its own widget, logic, and access rules.
• Excessive fields increase DOM complexity and RPC calls, reducing frontend performance.

✅ Solutions:

1. Split Views:
   Use multiple notebook pages (tabs) to group fields logically.
   Example: Personal Info | Financial Info | Technical Info
2. Use attrs with Conditions:
   Show fields only when relevant using conditional attributes.
   <field name="custom_field" attrs="{'invisible': [('type','=','company')]}"/>
3. Disable Unused Fields:
   Remove rarely used custom fields from the main view and show via smart buttons or related actions.
4. Load On-Demand (with widgets):
   For computed data, use widgets like statinfo or use kanban to summarize.
5. Backend Optimization:
   Avoid computed fields that auto-recompute on load unless necessary.
