I am going to use the DAAB to prevent a lot of manual labor in my database intensive application. But before I get started I would like to know if there would be any noticeable perfoemce differences between using the native ado.net datareader and the DAAB.
Most of your performance hit is going to be in the database reads/writes. That's true whether you use ADO.NET or DAAB, or any other DAL for that matter.
