I haven't been able to measure any actual speed difference on any machine
I have access to.  Maybe some years ago it made a difference, but it's lost
in the noise now.


PS: I also remember of a case where the precomputation was wrong because it
did not know that the menu was always going to be used when some other minor
mode was ON, and all the keybindings for the menu were provided by the minor
mode's map.  I can't remember the details, but my conclusion at that time
was that this specific optimization was not worth the trouble any more.
