title: Will indexing a SQL table improve the performance of a LINQ statement?
body: <p>Apologies for what may very well be a stupid question.</p>
  
  <p>I'm just intrigued as to (a) will indexing improve performance (b) how will it improve performance and (c) why will it improve performance?</p>
  
  <p>Also, if this does improve performance, would this be the case across the board for LINQ to SQL, LINQ to Entities, LINQ to Objects, etc, etc. </p>
  
  <p>Again, if this is a really stupid question, I do apologise.</p>
