# Composer has performance issues

## Symptoms

When editing a spot in the HTML Composer, performance slows down due to media preloading.

## Resolution

The following explanation and steps can help you identify and solve the issue.

### Understand media retrieval

In the spot, the `getElementWrapper` function from the [gfWizardBase library](https://docs.grassfish.com/docs/integrate-the-gfwizardbase) is used to get media data from the `ascData` field.

This function calls another function called `wrap`. When it handles a media element, it creates a DOM element called `clippedMediaHtml` using the `getMediaElements` function. This causes all related images and videos to load.

Loading all this media can slow down performance.

### Switch functions

To avoid performance issues, you can use the `getElementValue` function instead. It lets you access media data through `getMediaData`, without creating the wrapper.

This prevents the media from loading unnecessarily and helps improve performance.

```javascript
const mediaElement = window.gfWizardBase.getElementValue('Media');
const mediaDataObject = window.gfWizardBase.getMediaData(mediaElement[0]?.SpotId);
const mediaUrl = mediaDataObject?.FullFilePath || null;
```
