In emacs -Q, open a fairly big Scheme file (> 70k) and try to move in the file with C-n, C-f or mouse scrolling. It sverely lags for several seconds, doesn=E2=80=99t even respond to C-g. 2. Toggle font-lock-mode off through M-x, then try to scroll. It works as expected, no serious lags. 3. Running the profiler also shows font-lock as the culprit. This makes working on big projects, in my case the source code of GNU Guix distribution an impossible situation. I haven=E2=80=99t tried setting = up (Guile) Scheme with Tree-Sitter, but shouldn=E2=80=99t simple syntax-highlighting be not a serious problem?

No, it means the C files were compiled with -O0, which disables compiler optimizations, so my Emacs is supposed to be slower than normal. And yet I seed no lags with C-n, unlike what you report.

Ste= fan, what tools do we have to investigate slowness related to
parse-part= ial-sexp? Or maybe you have suggestions for how to speed up
font-lock i= n this case?

Hmm=2E=2E=2E `pars= e-partial-sexp` is normally expected to be fast, unless it
has to scan a= lot of text=2E

Here's the profile I get while moving with C-p through= the above file:

A stab in the = dark, but maybe the relevant call is the one in:

(state (i= f (or syntax-ppss-table
(not font-lock--syntax-= table-affects-ppss))
(syntax-ppss start)
= ;; If `syntax-ppss' doesn't have its own syntax-table and
= ;; we have installed our own syntax-table which
= ;; differs from the standard one in ways which affects PPSS, ;; then we can't use `syntax-ppss' since that would pol= lute
;; and be polluted by its cache=2E
= (parse-partial-sexp (point-min) start)))

so the origin of t= he slowdown would be the (?#=2E "w 14") in the setting
below in `scheme= =2Eel`:

(setq font-lock-defaults
'((scheme-font-lock-ke= ywords
scheme-font-lock-keywords-1 scheme-font-lock-keywords-= 2)
nil t (("+-*/=2E<>=3D!?$%_&~^:" =2E "w") (?#=2E "= w 14"))
beginning-of-defun
(font-lock-mark-block-= function =2E mark-defun)))

in which case, setting a `syntax-ppss-tab= le` should fix the problem, tho
we could also fix it by being more caref= ul: AFAICT the purpose of this
(?#=2E "w 14") is only to change the synt= ax of `#` from "prefix" to "word"
without changing the comment-related f= lags, so it shouldn't cause
`font-lock--syntax-table-affects-ppss` to be= set=2E
So, we could solve it by improving the code that sets
`font-l= ock--syntax-table-affects-ppss`, as in the patch below=2E

By setting to nil, it lets font-lock use `syntax-ppss` which means that on large buffers it tends to be much faster because it doesn't need to `parse-partial-sexp` all the way from `point-min` every time. > and what potential harm could happen if we install this? If it's set incorrectly, it can lead to messed up `syntax-ppss` state (because some calls use one syntax table and others use another) which could lead to mis-indentation, mis-fontification, incorrect highlighting of matched paren, incorrect buffer navigation, etc... Of course, these risks are confined to those buffers that use `scheme-mode` or a mode that derives from it. I believe the setting is correct for `scheme-mode`, but it's possible that some derived mode changes the `font-lock-syntax-table` and relies (incorrectly) on `scheme-mode` having already set `font-lock--syntax-table-affects-ppss` to t. This said, AFAICT this performance problem has been with us since Emacs-28 (commit cdadb7a97cbe), so it's not super urgent to fix it. I think we're fine with the fix on `master`. It would be nice to get confirmation from Divya that it does fix the problem he sees.

Your bug report was about Scheme files. If you see the "same" problem for (La)TeX files, I think it would be best to open a new bug report for it. IIRC, `font-lock--syntax-table-affects-ppss` can't be nil in `latex-mode` (or at least it's not clear how to do that without breaking something) because of how $...$ is paired (which doesn't always obey the nesting of braces).

I just checked and my compiled build was of an older commit. The variable was set `t`.

That's reasonable for the system. I do not notice any sort of lag with `M-v` on my system (Ryzen 7 5700G). Thank you Eli and Stefan for the prompt fix. Really admire the work you guys do.
