title: ASP.NET Dynamic Data performance issue
body: <p>I am experiencing performance issues with an ASP.NET Dynamic Data Entities Web Application.</p>
  
  <p>The application consists of 4 main entities. The tables contains between 100 and 8000 rows. I'm using the ListDetails view. Opening a single record takes 4 to 6 seconds on average, wich is not acceptable.</p>
  
  <p>The first thing I investigated was the performance of the database, but this was ok. Then I tried excluding the filters without a result. Finally I exluded most columns by setting the ScaffoldColumn attribute to false in the metadata classes. This gave a major result, loading forms in miliseconds. Then I started testing with more and more columns included. Everytime the number of columns increases, the performance gets worse.</p>
  
  <p>The number of fields for the main entities go up to 50. But isn't is strange that a form containing only 50 fields takes seconds to load?</p>
  
  <p>I hope someone has a good idea to boost the performance, or at least has a decent explanation for this behaviour. Thanks in advance!</p>
