I would expect the multibox test to be only a little faster, for reasons 
explained in my performance notes.

I would expect the Quesa logo to be significantly faster, especially if 
you increase the number of triangles by setting the subdivision style to 
constant (50, 50).

I'll do some testing on Windows.

After the 2 changes I just committed, transparency is working for me.

That model lacks vertex normals, so it's not on the fast path.  It also 
has lots of TriMeshes for no apparent reason, that is, they could be 
merged into one TriMesh.
