You still have to dig through 20+ screens of possible configuration values, some configs are in web.config in your app, some are in some other machine.config files, etc. The configuration just seems like a mess compared to your standard linux app with everything nicely organized in /etc/<app>

Not to mention the difference of opinions you get when you search for IIS tuning info/documentation. Half the stuff is only valid for older versions of IIS and there doesn't seem to be a lot of good info on the latest version when it comes to tuning.

You need to use the command line configuration tools, it has got a lot better than it used to be (thanks to Azure, I assume). Still nowhere near as consistent/logical as Linux, but it's getting better..
