===== Increasing Polygon Performance =====

In this video we will explore how to greatly increase your rendering performance by gridding your high point-count polygons. This technique is especially useful when you use a high point-count polygon such as a country or regional area as the ground color for your maps.  In many cases we see tile render times decrease from 500ms to under 5ms with this data optimization.  Included along with the video is a utility to help you grid your polygons.
