Unlike the 8-bit version, we need two iterations to process this within 128-bit vectors. This adds some extra complexity for pointer arithmetic and counting down which is unnecessary in the 8-bit variant. Accordingly the gain relative to C are just slight better than half as good with 128-bit vectors as with 256-bit ones.
