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.

You can find a complete performance test and sample code, please follow the link http://peterkellner.net/2009/05/06/linq-to-sql-slow-performance-compilequery-critical/ [...]
