There seems to be some performance issues related to drawing shapes on iOS. As an example, the Sandcastle Geometries and Appearances example loads the globe quickly but then loads each shape slowly. The globe is then very unresponsive after loading.
I’m not sure what the difference is but the examples listed under “Geometries” (e.g., Box, Circles and Ellipses, etc.) all seem to behave ok. Perhaps they just have fewer shapes?
I’m not sure if this is performance limitation of the device (I’m using an iPad), or if it is expected to work better. Can anyone with an iOS device confirm the behavior? I will keep investigating to see if I can pinpoint the issue.
Note that other Sandcastle demos seem to work fine.
