Anyone having performance issues with the android emulator (assuming you're not targeting assembly code) try creating a new AVD with the CPU architecture set to x86.

The new tool is currently available in preview, but it comes with the Visual Studio 2015 preview, so to get the emulator you’ll have to download the full package from the Microsoft Download Center.

Microsoft said support for the Android emulator will be coming soon, but didn't give an exact timeframe. Mac users can sign-up to be notified when it's available from the Visual Studio website.
