How did Samsung Focus outperform the Atrix?

[Noir]

I've been saying this time and time again during CES, despite the android love. Optimization. Android lacks it. Now there is proof (and not idle conjecture)
Windows Phone 7 still faster than NVidia Tegra 2 powered Motorola Atrix
the only issue with the video is that the wp7 device is not plugged in, but just for jokes and giggles I plugged in my device to A/C charger while the video played. And yet, even charging wp7 still outperformed the device in the video
Now this is a 1 gig ram dual core tegra 1 gig processor.
Discuss?
