my observations are that wkt.loads is faster than creating lines or polygons from list or tuples of coordinates. It's a bit unfortunate, but the only API to set a coordinate sequence are the CoordSeq_Set_X/Y functions and calling these thousands of times with ctypes is expensive. I already thought about implementing the geos_linearring_from_py function in cython or pyrex as an optional speedup, but I don't know if and how this works in combination with ctypes.
