The story there is I thought most of the page overhead was in the 
regular expressions of autop, etc so I thought that just reading the 
post text directly out of the DB would be faster, if less flexible.

The change was so small it was unmeasurable. It's a good example of why 
when tweaking performance it's critical to know where the actual 
bottlenecks are before getting your hands dirty. Premature optimization 
is the root of all evil.
