Then you are using it wrong.
If you want to use heavy antialiasing, you don't need to average so
many textures (supposing you are scaling the normals small).
If eg. 100 averaged textures look good without antialiasing, but you
are going to use heavy antialiasing for the final image, you can decrease
that count to eg. 20 or 10 or whatever.
The advantage is that it will produce a better result than a single
normal with the same antialiasing settings. Even two averaged textures will.
