It has been almost a year since I reported this problem.
Since that time, I haven't seen this issue anymore.
Closing it.

Verified in both emacs-27 and emacs-master

Recipe:
emacs -Q ~/save-buffer-slow.txt
;; insert few characters and run
M-: (benchmark-run nil (save-buffer))

;; Repeat several times: sometimes it takes a reasonable time, but
;; in others it takes huge time
;; (6-10 s to save a buffer with less that 50 characters)

It happens randomly.
I have been observed this maybe 1 week.  I don't recall to see this in
my other laptio runinning Debian 10, so it might be OS related?
