Bad performance for list render

[v1talii-dev]

Prerequisites

• [X] I have searched the existing issues
• [X] I understand that providing a SSCCE example is tremendously useful to the maintainers.
• [X] I have read the documentation
• [X] Ideally, I'm providing a sample JSFiddle or a shared playground link demonstrating the issue.

What theme are you using?

core

Version

5.x

Current Behavior

When the list contains a large number of elements (10000), the interface performance is poor. The result of the input operations or clicking on the list control buttons, you have to wait a few seconds.

Expected Behavior

Operations work without delay.

Steps To Reproduce

1. Open demo
2. Click "react-jsonschema-form DEMO" to go to the sandbox (link is very big for issue text editor...)
3. Input value in array object
4. Try to click move down/move up/delete button

Environment

@v1talii-dev Thanks for the example. We have some pretty large issues to fix before we get to dealing with performance. We'd welcome any help on this
