You can see the benchmark files here:

* <http://solarphp.com/svn/trunk/tests/Bench/Solar/Markdown.php>

* <http://solarphp.com/svn/trunk/tests/Bench/Solar/Markdown/>

Each iteration transforms the "Markdown Documentation - Syntax.text"  
file from the test suite.  Running on my 1.4GHz PPC Mac Mini (1 gig  
RAM), results are:

* benchSolarMarkdown ran 62075 iterations in 2 minutes (517/second)

* benchPhpMarkdown ran 125904 iterations in 2 minutes (1049/second)

So the functional/procedural PHP-Markdown is a little more than twice  
as fast as plugin-capable Solar_Markdown.  If you transform the  
source text anew on every page load, this might be an issue; if you  
cache the transformed text for subsequent page loads, it's probably not.
