Slower than C++ for sure, but depending on your needs it might still be
fine. I often set normals on meshes up to about 100k verts using Python.
To create your MVector array (in Python API 2.0), something like this will
do it in less than a millisecond:
normals = [om.MVector(0,0,1)]*100000
Creating your id list takes about a millisecond too:
ids = range(100000)
Then, like Christopher said:
mesh.setVertexNormals(normals, ids)
Trying it on a sphere with 40,000 normals, I can create and set all the
normals in 0.03 seconds.
