React server-side rendering - what is the performance impact of producing different html server-side to client-side?

If your serverside rendered html is slightly different to what's rendered client-side, you'll see some warnings in the console about it. What exactly is the performance impact of this on React? Does it matter? Or is it negligible?

From my practice it’s negligible.

The idea of react hydrate that it takes the server-side generated DOM and try to reuse it on maximum.

If there is a miss-match react have to render it on client side again, it’s not a big problem especially if its only the issue for deeply nested nodes.

Here is nice article on medium, check it ;)
