Performance Comparision of linq 2sql and Ado.net Entity Framework with stored Procedure?

Hi I am devloping the a asp.net site which will have lots of user online at a time. I am writing very efficient stored procedure for it. Which ORM tool should I use?

Ado.net entity framework or linq2sql?

Performance is needed as our requirement is to load every page in 4 seconds.
