Whatever takes the time isn't being cached, either, because it takes 11 seconds _every_ time I display it. Other pages are sluggish - to display Top takes about 3/4 of a second. In Emacs 21, Elisp's Index displays instantaneously enough. > Perhaps we need to reduce the amount of fontification that is done > on such a large node. But we have to do SOMETHING. Agreed. But it's not the fontification. -- Alan.
