I'd disagree here. OLEDB would be inherently slower only if you use the OLEDB provider for ODBC, where OLEDB's would be an additional layer of abstraction. When there is an OLEDB provider for a data source there's no inherent disadvantage of one over the other.

In fact, I've run tests that indicate OLEDB is faster than ODBC. I've done this for a VFP program that reads data from SQL Server where there is an ODBC driver as well as an OLEDB provider. In this case OLEDB is slightly faster on approx. 50K rows.

In the case of VFP data I must admit I haven't run any comparisons between the ODBC driver and the OLEDB provider, so if that's what you are talking about then this may not apply.
