To reproduce the issue, install company-mode, go scratch buffer
execute the code:
(company-mode 1)
(setq completion-styles '(basic flex)
company-idle-delay 0)
type
(rrrrrr) and then start deleting from the last r to the first one.
Observerd behaviour: the completion lags/feels slugish even in the
emacs -q setup(it gets slower if you load several packages).
The main offenders are:
completion-flex-all-completions + GC - on CPU profiler
completion-pcm--hilit-commonality - on Memory profiler
Thanks,
Ivan

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)
I seem to vaguely recall there being some improvements to flex
completion lately -- do you still see this problem in Emacs 29?

More information was requested, but no response was given within a
month, so I'm closing this bug report. If the problem still exists,
please respond to this email and we'll reopen the bug report.
