Hello, I was having serious performance problems on a Windows XP pro 32-bit OS running on a 2.4GHz Pentium 4 with 1 GByte of RAM. 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?
