App servers don't tend to maintain much global state, so are almost perfectly parallelizable. If you run out of CPU
there,drop another cheap box in the rack. 

Database servers aren't. Once you top out a database server your main options are to replace it with a bigger box
(increasinglyexpensive) or rearchitect the application (even more expensive). 

I'll always put more work on the cheaply scalable app servers if I can reduce the load on the database. Moving code to
thedatabase server for reasons of CPU cost (as opposed to, say, data or business rule consistency) seems an odd
approach.
