Answer 1

I had the same problem with IIS Express 10, Visual Studio 2015 Update 3 on Windows 10. I did a few tests and with different settings and browsers (Chrome 54, Edge 38, Opera 41). The browser doesn't really matter, but I found three things which significantly changed my original 15 seconds load time:

1. Switched Windows Defender 4.10 off (changed from 15 to 12 seconds)
2. Turned Edit and Continue feature off (changed from 12 to 6 seconds)
3. Switched Windows Defender 4.10 back (changed from 6 to 8 seconds)
4. Tried to run the application without debugging (changed from 8 to 2 seconds)

So if you are willing to give up Edit and Continue, or even debugging then you can speed up the process.

Edit and Continue can be turned off in Visual Studio/Tools/Options/Debugging/General/Enable Edit and Continue.

You can start your project without debugging with Ctrl+F5.

I would not recommend to turn off your Windows Defender, but you can play around with its exclude directory function, you might win a few seconds there as well.
