Linq to SQL: select optimization

Question

On large tables in MSSQL; selecting specific columns results in greater speed of the query. Does the same apply to Linq to SQL?

Would this:

var perso         


        

Answer 1

If you have columns that are very large such as binaries and images then it can make a significant difference which is why LINQ to SQL allows you to specify delay loading for certain columns so that you can still select entire objects without performing 'select new' projections.
