Regular views offer nothing from a performance standpoint. Views are simply replaced by their definition in the query submitted for execution and then optimized as if the query submittor had supplied the entirety of the view-query themselves.

For example, if I have a view named dbo.SomeData defined as:

CREATE VIEW dbo.SomeData

AS

SELECT ColumnName FROM dbo.SomeTable;

GO

and I say

SELECT * FROM dbo.SomeData;

this (in general terms) is what the query engine will eventually optimize after view-replacement is done:

SELECT * FROM (SELECT ColumnName FROM dbo.SomeTable);
