EaselJS: Caching

Giới thiệu

This example demonstrates the effect of DisplayObject.cache() and snapToPixel on performance. Caching can provide performance benefits for some types of content because the complex vector shapes do not have to be re-rendered each tick. Different browsers have different thresholds for when caching makes sense. The results for snapToPixel vary between browsers, but in general it will have no effect on the un-cached shapes, but a significant effect when cached.
