Not aware of one but I wrote the TextMate manual in Markdown and it is  
available here: http://svn.textmate.org/trunk/Manual/pages/en/

So this is a real-world example of Markdown use. I convert both each  
page individually and all of them for the printable version¹.

Example:

     % svn co http://svn.textmate.org/trunk/Manual/pages/en/
     % cd en
     % for f in *.mdown; do { cat "$f"; echo; } >> printable.mdown; done
     % time for f in *.mdown; do Markdown.pl < "$f" > /dev/null; done
     real 0m4.503s

This is on a 2.8 GHz Quad Core Intel Xeon (and using Markdown 1.0.1).  
75% of the time is spent on printable.mdown.

I btw have some references I normally append to the input, but these  
are not in the public repos. If you want to use the pages for a real  
benchmark suite and want the references, let me know.


¹ I actually concat the HTML versions, but for a benchmark it would be  
good with also a large file, and this one isn’t exactly contrived.
