Shapely uses the GEOS library for all operations. GEOS is written in C++ and used in many applications and you can expect that all operations are highly optimized. The creation of new geometries with many coordinates, however, involves some overhead that might slow down your code.

Shapely使用GEOS库来完成所有操作。GEOS是用C++编写的，并在许多应用程序中使用，你可以期望所有的操作都被高度优化。然而，创建具有许多坐标的新几何要素涉及一些开销，可能会减慢代码运行速度。
