After starting emacs fresh, its pretty quick. After around one day of using, the function takes more then 3 seconds to show the list of buffers and typing to match a buffer name still takes some seconds to register. The same issue happens on an older Notebook with emacs 29 (also sway). Thanks for any help. Jonas ^ permalink raw reply [flat|nested] 8+ messages in thread

How many open buffers do you have? M-: (length (buffer-list)) RET will tell you. If it's an unusal amount, you can eval (dolist (b (buffer-list)) (message "%S" (buffer-name b))) <=== C-x C-e here! in order to print all buffers' names to *Messages*. My guess is you use some package which creates buffers over buffers without cleaning up. Bye, Tassilo ^ permalink raw reply [flat|nested] 8+ messages in thread

Have a look at the Emacs profiler, e.g., the commands profiler-start and friends. There's surely also a section in the manual. That should show where the time is spent.

You can expand the tree below command-execute by clicking on the + sign. But note that the time (22secs) also contains the time Emacs waited for your input.
