My Windows 7 development stack is 64-bit Java and Galileo, native (no linux virtual machine) and has about the same 1-minute performance you describe to start the emulator and app. But once you get it running, you don't need to shut it down to start an updated version of your app - it will hot-swap the .apk and restart it pretty quickly.

The Android emulator stalled when I tried to invoke the HelloAndroid test app. It took at least 5 minutes to display "Hello, World". I setup Android on my Windows 7 pro 64-bit machine. I downloaded 32-bit Ubuntu Lucid Lynx 10.04.1 to a VirtualBox on this machine. I gave the Ubuntu OS 5.25GBytes of RAM and 20GBytes of harddisk in the VirtualBox. I downloaded 32-bit eclipse Galileo 3.5.2 onto Ubuntu. I downloaded the 32-bit Android sdk and Android ADT plug-in. The VirtualBox is running a 32-bit OS and emulating a 64-bit OS. When I run Android on top of eclipse Galileo in the setup, it takes 1 minute for the "Hello, World" to appear in the emulator window. The emulator appears to hang-up, but if you press the MENU button on the emulator, the UI will respond and un-freeze the display. I've searched the internet, and I don't think this emulator every runs faster than about 1 minute to load and display the apk. Has anyone had better performance than I have had?
