You may also want to check out the PageCache plugin, it does something 
similar by storing the fully rendered page in cache, and serving from 
cache on subsequent requests.  The page can be deleted from cache when 
the content has been changed or after a certain time interval has passed.

The fully static method will be faster of course, but not too much 
faster. ;)
