the ORM is going to be slower in all cases since there is the overhead of creating new object instances and populating them, as well as initializing their attribute instrumentation and also a copy of their attributes for the purposes of tracking changes when you issue a flush() statement.
Couldn't an approach like dbrow (http://opensource.theopalgroup.com/) bring some benefit in this area? It surely overlaps here and there with SA, but expecially thanks to the C impl (there's also a pure Python one) it's pretty fast in delivering lots of instances of the same class.
