title: After enabling IIS 7.5 autostart, first request is still slow
body: <p>I've set startMode="AlwaysRunning" attribute on my application pool and serviceAutoStartEnabled="true" attribute on my application in IIS configuration. I've even set up serviceAutoStartProvider and can see that "warm up" code is being executed. I also can see that w3wp process auto-starts after iisreset. Still, the first request to my ASP.NET MVC application is exactly as slow as without auto-start. Is there any point I'm missing or any way to easily debug this without a profiler?</p>
  
  <p>Is this feature expected to affect first request performance at all? What is actually the bulk of work to do on the first request, given that the worker process is ready, .NET appdomain and even all .NET assemblies have been loaded?</p>
