# Performance optimization

This section describes common performance issues and optimization techniques.

## Hidden Components

If you have many hidden components and are experiencing performance issues, this could be an area for optimization. Most of these issues can be resolved by setting the component's S*how Condition* hide mode to **Not rendered**.

By default, all components use the **Hidden** hide mode, so they are rendered during page initialization but remain hidden. Using the *Not rendered* hide mode instead will prevent them from being rendered during page initialization, and they will only be rendered when they become visible.
