Unfortunately, I'm not as optimistic as you on that one.
In any case, s-p-f is unlikely to help there. ¯\_(ツ)_/¯
So here's the first bug report about a random slowness in CC Mode:
Thank you.
. visit src/w32.c on the emacs-27 branch and go to line 8747
. C-e DEL -- this deletes the last 'e' of "else"
. the following line gets immediately fontified as a function name
. type 'e' -- then watch how the fontification of the next line to
its original face takes almost 1 sec -- this is the problem
I can and can't reproduce this at the same time.
Meaning, I do see "fontification of the next line to its original face"
take some time. But if I don't wait for it to turn black again and
continue typing, nothing bad happens: Emacs continues reacting to input
just as promptly, and the next line turns black soon enough.
And if I type e.g. 'e RET', or 'e SPC', the next line turns black
seemingly instantly.
FTR, this is in Emacs 27.0.90 built with -Og, but a -O2 compilation of
Emacs 26.3 takes only slightly less time in this case.
'emacs -Q' and a '-Og -g3' build of 27.0.90 here.
