Be static my friend.
I have a blog written in my "micro" framework [1] that doesn't use any caching, and is hooked up to MongoDB, it has handled being #1 a few times without falling over, or even slowing down.
The secret? 1 query per page that pulls all the relevant information into the view model. Also has a hidden benefit that I can count my pageviews by just looking at the number of queries against mongo for the day.
