There *are* template-related problems on en.wp at the moment, discussed in the thread from http://lists.wikimedia.org/pipermail/wikitech-l/2007-October/034323.html, but I'm still not sure that's an indication that additional limits are needed - but it might be.
Also relevant are the threads at [[Wikipedia:Village pump (technical)#any work on the incredible sluggishness of deeply edited articles?]] and [[Wikipedia talk:Reference desk#Houston, we have a problem.]], and Simetrical's statement at http://lists.wikimedia.org/pipermail/wikitech-l/2007-October/034338.html in the aforementioned thread that "This is the sort of thing that the wikitext include limit was supposed to prevent".
The question is, how true is it that "almost every very-high-traffic page on Wikipedia is having extreme problems right now". I suspect not, but if so, is it because there are more pages with say, heavy use of the {cite} template, or because templates like {cite} have gotten more complicated, or because template interpolation has somehow gotten slower, or simply because there are more hits and edits being processed every day, such that our headroom is going down?
