How often does the data change and how critical is it to have real-time 
results.  Web sites often have thousands of people getting copies of the 
same thing, or at least computed from the same values even if they are 
the same only for a short period of time. One approach is to put 
memcached between your web application and the database for extremely 
fast repeated access to the same data. It is just a cache layer, though, 
you still need a persistent database underneath.
