Interesting numbers. PHP Markdown has been optimized quite much, it'd  
probably be hard to beat, speed-wise, for another PHP implementation.

I'm preparing a version of PHP Markdown which is more extendable too,  
and it'll probably be as fast as the current version. The idea is  
very simple: change `runSpanGamut` and `runBlockGamut` so that they  
execute a configurable list of functions instead of the hard-coded  
process we have today. This way, a subclass of Markdown_Parser will  
be able to add its own functions wherever it wants without having to  
redefine the gamut function entirely.

I'm also changing the way span elements are parsed to prevent  
**things *like** this* from generating invalid markup. It may or may  
not be slower once ready since I'm also removing other code obsoleted  
by the process.

Interesting: I just found out that Solar Markdown is using the HTML  
Tidy library (built into PHP 5) to fix bad XHTML at the end of the  
process. That's clever. How come you've not mentioned it before? :-)
