Why is ADO.NET faster?
Because ADO.NET always establishes the connection directly to the database. That's why it provides much better performance compared to the Entity Framework. It is because, in Entity Framework, the entity first translates the LINQ queries to SQL and then it processes the query to perform database operations.
