Ikiwiki has already been optimised a lot, however.. * Look at splitting up CGI.pm. But note that too much splitting can slow perl down. > It's split enough, or possibly more than enough, now. :-) * 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. > Seems to be O(Num Pages * Num Links in Page), or effectively O(N) > pages for most wikis.
