The performance improvement depends on the attribute type, domain size,
and whether the cached vert to face map is used for something else like
vertex normal calculation during evaluation. In a simple test with a
large cube, I observed a 6.7x improvement in overall FPS for a 4x4
matrix attribute, a 1.12x improvement for a float attribute, and
roughly equivalent performance for booleans.
