I'd like to think that a well designed system can serve dynamic pages
almost as fast as static ones.  If the page says "Hi <username>" at
the top, all it really needs to be doing is concatenating a few
in-memory strings together before serving the page.

The one way where static might win is if mod_gzip is a big cpu load.
You could cache pages in compressed form.  However, even that may not
matter much.  I believe gzip format lets you concatenate compressed 
strings or files together, and still have them uncompress properly.
