True, `after-find-file' does this:

 (or not-serious (sit-for 1 t))

And indeed that accounts for 1s of the ~2.5s delay; so this is
a significant factor, yet seemingly not the only issue.

With that commented out I now get:

Elapsed time: 0.835925s (0.039518s in 1 GCs) ;; find-⁠file-⁠noselect-⁠1
(1.7317769889999999 1 0.03951770099999996)   ;; the overall 
benchmark-run

Instead of the former:

Elapsed time: 1.876737s (0.057295s in 1 GCs) ;; find-⁠file-⁠noselect-⁠1
(2.680159853 1 0.057295379000000146)         ;; the overall 
benchmark-run
