Direct OLE DB C++ consumers (e.g., ATL OLE DB Consumer templates) achieved near-native performance. However, going through ADO added a thin but measurable layer. By contrast, ODBC remained faster for purely relational, bulk operations because of its simpler calling convention and lack of COM reference counting per column access. However, going through ADO added a thin but measurable layer

OLE DB introduces a sophisticated, albeit complex, model for query execution: ODBC remained faster for purely relational
