Using Fiddler to ‘slow down’ your network connection

I’m working on a Windows 8 application and I need to test its behavior under relatively slow network connections in order to optimized user feedback. After some investigation I remembered that Fiddler offers such options.
Just run Fiddler, and select Rules->Performances->Simulate Modem Speeds

And you’re done, your Windows 8 app magically slows down…

Don’t forget to remove it when done!
