I tried this on my system (with the test file provided).
The test case is:
(benchmark-progn
(while (not (eobp))
(call-interactively #'next-line)))
normal 25s
+1 31s
+2 25s
So basically, they're all more or less the same now, so I'm guessing
that whatever Mark was seeing in Emacs 25 has gone away now (as Emacs
has gotten a new font backend etc), so I'm closing this bug report.
If this is still an issue in Emacs 27, please reopen.
