[djmips]

CPU wise - although you can optimize specially for the ARM - and it's great to make sure your math is using NEON and that you don't have some pathological slow down because your code assumes more cores you'll still find the lions share of your optimization on CPU benefiting both architectures.

For fun, I'll mention that there is a hardware hash function that you can use. The public A57 documentation has a performance guide available that is applicable to the Switch.
