I mentioned earlier I've been trying Ubuntu for Android development, and today I'll try to capture the difference in performance of the Android emulator on the two platforms. I haven't seen much difference in terms of Eclipse performance, but when it comes down to the Emulator it is quite obvious.
I'm not quite sure what makes the difference so large, might be the OS or maybe the QEMU software implementation on each OS. I chose to test with Android 4.2.2 AVD images just to push it - older versions like Android 2.1 or 2.3 seem to work better.
Also I'm running the tests on my home Dell laptop which is a few years old, making the difference even more obvious. I find Windows 8 on this machine faster than Windows 7 and generally a pleasant experience while probably on par with Ubuntu 13.04 in terms of performance.
While I find Windows more familiar and easier to use, because of the poor Android emulator experience on Windows I find using Ubuntu a less annoying experience for this particular task.
Performance on the Phone AVD is acceptable although slightly laggy, using Intel HAXM 1.0.6 and "Use Host GPU" option. My GPU chip / driver don't seem to support OpenGL 2.0 (1.1 only?), showing in the startup messages.
For Nexus 7 AVD, I had to drop down the RAM to 512 MB to get HAXM working with it, maybe because I configured HAXM earlier to only use 512 MB, trying to avoid the system running out of memory (only 4 GB of RAM). The experience is laggy (1-2 seconds wait between activities), barely usable - disabling animations helps a bit.
Emulators start in seconds (15-30) to desktop, compared to minutes (1-3) in Windows!
Phone 4.2 AVD is quite snappy, and haven't done anything special for it like install KVM. No additional messages at startup. AnTuTu shows same OpenGL 1.1 on screen during testing, but the FPS is much higher (~60 fps)!

Nexus 7 AVD starts quickly and it's very snappy! Navigation through activities and scrolling is very responsive, a huge difference from Windows. Some error messages at image startup though:
