### Describe the bug

We are experiencing extended waiting times for server responses when utilizing next/image. This issue occurs sporadically, and I suspect it may be connected to the cold boot of the `next/image` lambda function. Consequently, our image loading performance has been severely impacted.

Here is an example of the issue:


This image is only 15KB in size, yet it takes a full 6 seconds to download. It's worth noting that we are also using the `webp` format for our images.

### Expected behavior

Images should load as quickly as possible and not be delayed due to server response times.

### Reproduction steps

1. Create a next.js app
2. Import some static images using next/image
3. Deploy the app on Amplify
4. Evaluate the performance of image loading (observe the presence of cold booting for images).
