I have used it to apply all "the_content" filters to the content and 
then store the filtered output.  This is what TextPattern does (or did, 
last time I checked).  Some filters are VERY expensive to run realtime.  
Textile 2 in PHP is a monster... so much so that your main page or 
monthly archives may refuse to load on some servers.  So what you can do 
is have the Textile 2 filter run when you edit or publish an entry, and 
then you'll just directly output the processed content.

I did some work on a plugin that someone wrote last year that did this:


If you're running Textile 2 or another expensive text-processing engine, 
it could make your pages load a lost faster.
