title: Reduce PostSharp compile time overhead
body: <p>We recently introduced <a href="http://www.postsharp.org/" rel="nofollow noreferrer">PostSharp</a> into our code base and the compile time of our ASP.NET MVC project has doubled to quadrupled.  We have about 3 MVC projects and approximately 8 class library projects in our solution.</p>
  
  <p>Obviously there will be overhead associated with PostSharp since it is <a href="http://www.postsharp.org/aop-net/compiletime-weaving" rel="nofollow noreferrer">modifying the MSIL code</a>.  But a 2x to 4x overhead is quite an overhead. </p>
  
  <p>Is this typical with PostSharp?</p>
