I'm curious if anyone has collected performance metrics of World Wind Web? I'm considering using WWW in one of my applications, but I need to get a feel for what kind of response times there are. If I put 1000 entities on the map, how does that nominally impact the render time? Obviously this would be GPU dependent, but are there any baseline number for common GPUs? There are also different types of objects that can be displayed like an HTML5 Canvas, a PNG, SVG or collada? I'm looking for metrics to help decide which is the best format for my objects, and if there are any good caching strategies to improve the performance.
