Perhaps.

I'm not quite sure what's the culprit in Markdown.pl, although I  
suspect the overuse of the HTML block parser to hash Markdown- 
generated markup is part of it. That's one thing I've removed in the  
many architectural changes PHP Markdown passed through since version  
1.0.1d.

Today I only fixed an issue in some part of *my* code, a part that  
doesn't even exist in Markdown.pl. I'm pretty confident that porting  
my architectural changes to Markdown.pl would improve it a lot, both  
in terms of speed and for squashing bugs. If anyone wants to do it,  
you can ask me for directions.

Sure. 49 seconds (for the 176 Kb document). Oh, and parsing the  
double-sized document (352 Kb) took 289 seconds (almost 5 minutes!).  
That's clearly not linear.
