title: IIS 7.5 web application first request after app-pool recycle very slow
body: <p>We have our website running on two machines with iis 7.5
  One works fine.</p>
  
  <p>The other one how ever takes a really long time to process the first request after an app-pool recycle. It can take upwards of 60secs which is unacceptible since its going to be used as our production server.</p>
  
  <p>I've checked the app-pool settings on the both servers and they are the same, and the webapp version on both servers is the same.
  I've run the task manager and resource monitor, add see a connection to the machine when I make the request but nothing else happens, iis doesn't even show the request in the logs untill its completed.
  I don't really know what its doing in the mean time.</p>
  
  <p>Are there any traces of settings we can try to play with to fix this or find the problem.
  It's very puzzling. </p>
  
  <p>EDIT:
  So I've got some more information now, finall got the failed request logs to work (had to give the user IIS_IUSRS permissions) but I've got some logs to see whats going on</p>
  
  <p>The time lost is inbetween two seconds in the log file.</p>
  
  <pre><code>1. MODULE_PRECONDITION_NOT_MATCH    Name="ScriptModule-4.0", Precondition="managedHandler,runtimeVersionv4.0"            12:09:46.422 
  2. VIRTUAL_MODULE_UNRESOLVED        Name="FormsAuthentication", Type="System.Web.Security.FormsAuthenticationModule"     12:12:04.390 
  </code></pre>
  
  <p>As you can see it takes over 2 minutes inbetween those two events, anyone encounted this before?</p>
