I put Lexical through Hog Bay's Moby Dick test [0] (paste the entirety of Moby Dick, scroll to the middle, and try editing). It didn't pass. AFAIK, only ProseMirror passes, albeit with some lag.

We have some important changes landing soon that will make insertions O(1) rather than the current O(n) - so this will greatly improve performance.
