In "emacs -Q"? If so, it didn't happen to me. I tried both the Segoe
Symbol font (which nowadays includes all the Emoji, so the Emoji font
is not needed), and the Segoe Emoji one, and saw no slow-down.
So some other factor is at work here.

How can an Emoji font be a fallback for the entire range of Unicode
characters? It's not what it's for.
