-* Render each changed page only once. Currently pages are rendered up to 4
- times in worst case (8 times if there's an rss feed).
+Ikiwiki has already been optimised a lot, however..
- The issue is that rendering a page is used to gather info like the links
- on the page that can effect rendering other pages. So it needs a
- multi-pass system. But rendering the whole page in each pass is rather
- obscene.
+* Look at splitting up CGI.pm. But note that too much splitting can slow
+ perl down.
-* Don't render blog archive pages unless a page is added/removed. Just
- changing a page doesn't affect the archives as they show only the title.
+ > It's split enough, or possibly more than enough, now. :-)
-* Look at breaking the relatively rarely used blogging stuff out of
- Render.pm, into its own module.
+* The backlinks calculation code is still O(N^2) on the number of pages.
+ If backlinks info were stored in the index file, it would go down to
+ constant time for iterative builds, though still N^2 for rebuilds.
-* Look at splitting up CGI.pm. But note that too much splitting can slow
- perl down.
