This sentence is a big red flag for me. An analysis of a stategy that pushes work towards a subsystem, and then purposedly ignores the perforance implications on that subsystem is methodologically unsound.

Personally, I am all for using the DB and writing good SQL. But if I weren't, this argument would not convince me.
