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. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
