List scrolling performance in Windows Phone Mango demoed

While the native applications are silky smooth in Windows Phone 7 the same can not be said of 3rd party apps, which do not have access to the native SDK used by Microsoft, but rather have to use higher level and slower languages like Silverlight.

Microsoft is however determined to close the performance gap between native and 3rd party apps, and in the above demo appears to have done just that, with changes in the Silverlight controls in Mango resulting in much smoother list box scrolling than previously, even when there are many images on the page.

Rene Schulte, who appears to have a developer device, notes:

As you can see, it’s quite a huge difference and even this Mango prebuild  runs very smooth on this rather old ASUS hardware. There’s still some room left for more improvement, like the rasterizer, but imagine the boost on production devices with the final Mango version.
