> If the editor is laggy it is because of the server / infrastructure you are using, not the editor. I can guarantee this as a fact.

Gutenberg is react based client side thing. The lags while typing in Gutenberg cannot be due to the server.

I said server or infrastructure, meaning server or client-side machine / browser. Essentially, their hosting or local environment. The code loading in their browser which is causing the lag is the same code for everyone else, and this is not a reproducible issue in the WP community. If this person's account of things is accurate, then any lags in Wordpress would be a local environment issue.
