I recently became annoyed enough in my 1000-buffer Emacs instance to start profiling things. I was disappointed to find that the buffer-switching slowness I'd seen is the fault of ido-switch-buffer. ido-switch-buffer takes over a second before it starts accepting user input, with this many buffers.
Which Emacs version are you using?A fix that seems relevant has been added in df4991093b9 recently. But it's only in Emacs 28 thus far.
