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?
