So I added a few print statements to my copy of the 3D viewer in order
to figure out why the 3D viewer was so slow...
The results were very interesting.

I think one of the easiest optimizations is to add some kind of
application-wide cache in RAM such that

Hi Andrew,
Caching the meshes including normals on disk could speed up loading even
further:

Good idea.
Let me work on getting a RAM cache working first, then we can update the
"load file from disk" code later on.
