Your test is incorrect. In LINQ you select a list, in ADO you using a SqlDataReader. I used your test and my results:
ADO SqlDataReader: 0.44
ADO Type DataSet: 0.98
LINQ TO SQL, to list: 1.09
LINQ TO SQL, foreach: 1.03
So, if you use DataSet or LINQ TO SQL in application, differences of the performance are minimal

Hi, i need a clarification, am using 5 table information in a single query, i have used 3 tier Architecture, in this 3 tierarchitecture i used to get the complete data from the each table in to a LIST, then i will write a LINQ Query by using these 5 LIST, assuming each table has 5 thousand Records. Will this Task reduce the performance of the application?, howmuch time will it require than normal ADO.Net.
PlZ Reply…. i need it Urgently, Thanks in Adv…. Preetham K A.

It seems to me no matter what method you use, LINQ will always be massively slower than using stored procedures to execute sql commands and then allowing ado.net to retrieve the results. Am I missing something?

Everyone’s talking about Linq-To-Sql…
what about Linq to object collections?
Xml??
with 0 optimization there… it suffers like HECk!
