Emacs exit is slow when auto-complete-mode is enabled

I too am observing this emacs-29.3. I moved mv ~/.emacs/ac-comphist.dat{,.bk} and that seemed to address the slowness, albeit losing history I guess.

Can you try to profile it? 🤔

[ioah86]

Sure... As far as I know, there are multiple ways to profile in Emacs... If you can let me know the way you prefer to profile, and what exact files/outputs you are looking for, I am happy to do it.

[jcs090218]

Yeah, it's a bit tricky to do profiling when exiting the Emacs. Can you try disabling auto-complete before exiting emacs? You should be able to shutdown without any slow down.

The culprit is ac-comphist-save(). I've tried to profile it with profiler-start and profiler-report, but I'm not getting useful results (just command-execute).
