We now use web assembly for triangulation for the majority of use cases.Īs you can see in the example below, this Arctic sea ice layer loads over 5x faster than the same layer in 4.20. Complex polygonsįor complex polygons with a large number of vertices, layer draw time has significantly improved.īehind the scenes, we added a new simplification algorithm to preprocess the geometries and optimize memory management.
These improvements are focused on polygon features and maps with multiple layers. Version 4.21 introduces many performance improvements that will decrease the draw time of your layers.
