The rust implementation has a lot that is very naive from a performance point of view. Every sphere is allocated separately on the heap, so every sphere hit would have to hop through that sphere's pointer. There is actually a fairly simple C++ version that was made as part of the original book. It also does a lot that is naive from a performance standpoint, but that's what I would think people would want to use a baseline.
