Performance Problems

Symptom

Component loads slowly or causes performance issues on the Lightning page.

Common Causes and Solutions

1. Too Much Data Loaded

Check: Component may be retrieving thousands of records unnecessarily.

Solution:

• Implement pagination in component configuration

• Add record limits to reduce data volume

• Use more specific filters in data source settings

• Consider loading data on user interaction rather than on page load

2. Multiple Components on Same Page

Check: Too many App Builder Components on a single Lightning page can impact performance.

Solution:

• Limit number of components per page (recommend 3-5 maximum)

• Use tabs or collapsible sections to organize content

• Consider breaking into multiple Lightning pages

• Remove unused or redundant components

3. Complex Data Relationships

Check: Components displaying related list data or complex object relationships.

Solution:

• Simplify relationship queries

• Reduce number of related fields displayed

• Use summary fields instead of detailed lists

• Consider using Lightning related lists for complex relationships

4. Large Record Result Sets

Check: Component configured to display too many records at once.

Solution:

• Reduce default number of visible records

• Enable pagination or "load more" functionality

• Add filters to narrow down displayed records

• Set appropriate default filter criteria

Note: App Builder Components are designed for lightweight, focused use cases on Lightning pages. For complex, data-intensive applications requiring advanced performance optimization, consider using Dynamic Components, which offer more granular control over data loading, caching, and rendering optimization
