Description
Steps to reproduce 🕹
I have a long list of people (1000)
Each of them has a checkbox status attach to every user
I did notice when I use HTML checkbox instead of MUI one, the page renders about 3 to 5 times faster
The issue only occurs when I'm dealing with a long list of players, it does not affect a short list of players,
at least from the visible standpoint
Repository with live reproduction:

Current behavior 😯
Checkbox takes a while to update the page
Expected behavior 🤔
Checkbox works immediately
Context 🔦
Demo:

I would like any help on this one, I might be doing something stupid from the React optimization standpoint, so I'd appreciate any advice

Research direction
Use the linked react-slow-render repository as the reproduction and compare the MUI Checkbox with the native HTML checkbox in the 1,000-player list. Profile the Checkbox update path first; done means the long list updates promptly without the reported 3–5× slowdown, with behavior preserved.
