Yes, I know that. But can you point to a particular node in a particular manual that you find is too slow? I checked (using `T') all of the manuals that come by default with Emacs on Windows - I found no nodes deeper than 4. I didn't check each level 4 node in each manual, but I checked several, and I see no performance problem. Perhaps you can find a level 4 node whose levels 1-3 are in different subfiles, and you can check whether it is too slow? IOW, is this a real problem in practice or just a hypothetical problem? > > We have only a certain number of possible heading levels, > > and it works fine for those, AFAICT.
