Is Entity Framework faster than stored procedures?

The overall winner is Stored Procedure, where Stored Procedure won 3 times while Entity Framework won 2 times.

We can see right away that LINQ is a lot slower than raw SQL, but compiled LINQ is a bit faster. Note that results are in microseconds; real-world queries may take tens or even hundreds of milliseconds, so LINQ overhead will be hardly noticeable. … Why compiled LINQ is faster than raw SQL?

Is Ado net still used?

So yes: there’s definitely still room for “classic” ADO.NET to “fill the gaps” where EF/L2S or other technologies don’t really offer anything useful. Older applications still use classic ADO.Net.
