## Performance Considerations

### Database Optimization

- Comprehensive indexing on all foreign keys
- Indexes on status and date fields
- Prefetch related objects in API views
- Select related for foreign keys

### Query Optimization

- Uses `select_related()` for single relationships
- Uses `prefetch_related()` for many relationships
- Filters at database level
- Pagination for large result sets

### Caching Recommendations

Consider caching for:
- MDT statistics (cache for 1 hour)
- User pending notes (cache for 15 minutes)
- Department participation (cache for 30 minutes)
