-I'm not sure where the bottleneck is for running ikiwiki over a site like my blog [Natalian](http://source.natalian-org.branchable.com/?p=source.git;), though I like to think the markdown processing could be speeded up by the support of the C implementation of Markdown called [Sundown](https://github.com/tanoku/sundown).

+>>> markdown rendering by up to 40x, although when building a site ikiwiki
+>>> in practice does other work, so the gains are less impressive. Building

+>>>> Thanks for doing this; it's given a well-needed speedup to my huge site.
