# Performance & Optimization

### Performance Issues with Dynamic Components

#### Symptom

Component loads slowly or causes performance issues on the page.

#### Common Causes and Solutions

#### 1. Too Much Data Loaded

**Check**: Component may be retrieving thousands of records unnecessarily.

**Solution**:

* Implement pagination
* Add query limits
* Use more specific filters
* Load data on-demand rather than on page load

#### 2. Complex Nested Components

**Check**: Deeply nested component structures slow rendering.

**Solution**:

* Simplify component hierarchy
* Break into multiple smaller components
* Reduce nesting levels
* Optimize component structure

#### 3. Inefficient Queries

**Check**: Multiple queries or inefficient SOQL.

**Solution**:

* Combine related queries
* Use relationship queries instead of separate queries
* Add selective filters
* Index custom fields used in filters
