Update panels are designed to perform partial post back eliminating the need for doing a complete post back for updating a part of the page.

Microsoft .net framework 3.5 introduced the Language Integrated Query (Linq) feature. Linq provides a set of query operators to filter, join and perform other such data related operations on various types datasources such as lists, dictionaries, datasets etc.

In this article we perform a simple filter operation on a collection of data stored in a list using the traditional foreach loop method and the linq method and compare the performance statistics.
