I cannot reproduce this in "emacs -Q" with today's master. Do you have any customizations related to scrolling? This further input from you: > Also, when point reaches edge of screen Emacs instantly shows you next > portion of text so point gets in the middle of the screen, instead of > just showing you one more line. ^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ seems to indicate that you have customized scrolling, because by default Emacs does not scroll just one line. Perhaps you have scroll-conservatively set to a large value; if so, I'd indeed expect some slowdown when the font size is changed, because supporting scroll-conservatively is sometimes costly, especially when the last displayed line is only partially visible. So please try this in "emacs -Q" first. Thanks.

I indeed have some customization of scrolling, but it's not =E2=80=98scroll-conservatively=E2=80=99, its value is 0. I can reproduce it with =E2=80=98emacs -Q=E2=80=99, although my Emacs build= is a bit older then current master. I'll try with master.

No it doesn't. I tried it with normal text, something from my configuration. I can only tell that it happens even when text doesn't have long lines (beyond 80 characters). Just checked this out.

One way to measure it is to write a simple Lisp function that scrolls with next-line to the end of a long buffer, and measures the time it takes to do that. Then run it and show the results. (Some slow-down is expected because a larger font with the same window dimensions means more scrolls, but you can alleviate that effect to some extent by enlarging the window to have the same number of visible lines.) > > Also, what text is in the buffer that you are using in your recipe? > > Does it use more than one font? > > No it doesn't.

Setting =3D=3D=3D=3D=3D=3D=3D To measure how long it takes to scroll a long buffer from beginning to end with =E2=80=98next-line=E2=80=99 command the following code was evaluat= ed: (defmacro with-timer (title &rest forms) "Run the given FORMS, counting the elapsed time. A message including the given TITLE and the corresponding elapsed time is displayed." (declare (indent 1)) (let ((nowvar (make-symbol "now")) (body `(progn ,@forms))) `(let ((,nowvar (current-time))) (message "%s..." ,title) (prog1 ,body (let ((elapsed (float-time (time-subtract (current-time) ,nowvar)))) (message "%s... done (%.3fs)" ,title elapsed)))))) =20=20 (defun next-line-racer () "Scroll till end of buffer with `next-line' and measure how long it tak= es. =20=20 To make it realistic `next-line' is called interactively." (interactive) (with-timer=20 (while (not (eobp)) (call-interactively #'next-line)))) The file used: https://github.com/Fuco1/smartparens/blob/master/smartparens.el which is 7992 lines long. The Experiment =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D The file is opened and cursor is at the beginning of the file. Font size is either altered with =E2=80=98C-x C-=3D=E2=80=99 (increased, denoted in r= esults as +1) or =E2=80=98C-x C--=E2=80=99 (decreased, denoted in results as -1) or not a= ltered at all. No adjustments to compensate number of visible lines were performed in this experiment because I think difference wouldn't be noticeable. Then =E2=80=98M-x next-line-racer=E2=80=99 is called. Emacs seemingly freez= es for some time until it shows the point (cursor) at the end of the buffer and message in mini-buffer displaying time it took to accomplish the scrolling. No demanding processes were run in the background during the experiment. The Results =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Here I post measured times: Font Size Time in Seconds normal 301.423 +1 1055.157 -1 487.935 Hope it helps.

Here are my times: Font Size Time in Seconds ELisp Fundamental normal 139.9 113.2 +1 140.4 112.2 -1 282.0 126.4 -2 148.8 +2 114.4 The second column of numbers is with the same file, but with font-lock turned off, after rejecting the file-local variables, and in Fundamental mode. As you see, the differences are much smaller in Fundamental mode. This points to face remapping as the possible reason for slower redisplay, at least in my case. When you enlarge or decrease the default font size, Emacs needs to look up the faces in face-remapping-alist each time it needs to redisplay something, which could explain some slowdown. I don't know why the +1 case is so much slower on your system; perhaps you could use some kind of profiler to see what takes most of the time in that case. You could start with the Emacs's built-in profiler, although I doubt it will tell something revealing, because I think the reason is below the level the built-in profiler can look. In any case, I understand now why you perceive the slowdown as significant: if it takes 1000 sec to scroll through a 8000-line file, it means you get just 8 lines-per-second, which is slow enough to annoy. As you see, on my system, I get 5 times faster performance, which is below human annoyance threshold.

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.
