[wp-hackers] Post title in comments feed in 1.5.2

[Michael D Adams]

Actually, there is caching for is_single comments feeds.   
permalink_single_rss() (the title link) caches the post in question.   
Which makes me wonder if the is_single || is_page feeds could be made  
more SQL efficient. (Note this isn't true on is_page feeds - looks  
like a bug).

That's the only place I see any caching.  Otherwise, I suppose the  
idea is that the feed knows *exactly* what information it will  
require, and so it doesn't need to cache anything.  It just grabs  
what it will need: no more no less.

Which method is actually more efficient in terms of speed on a  
typical box (several smaller, non JOINed queries or one larger JOIN  
query), I don't know.
