Slow rendering of image in react Native

Image is downloaded , but still rendering very slowly, anyone knows what can be happening?

enter image description here

here is my code:

import React from 'react'
import { StyleSheet, Image, Text, View } from 'react-native'
import Backgroundimage from '../../../assets/images/backgroundImage.jpg'

export default function ImageContainer() {
return (
<View style={styles.ImageContainer}>
<Image source={Backgroundimage} style={styles.Backgroundimage}/>
</View>
)
}

const styles = StyleSheet.create({
ImageContainer: {
display: 'flex',
width: '100%',
justifyContent: 'center',
alignItems: 'center',
},
Backgroundimage: {
height: 450,
width: '100%',
}
})
