    CPU

    " On a 32 bit CPU SHA-224 and SHA-256 will be a lot faster than the other variants because they are the only 32 bit variants in the SHA-2 family. Executing the 64 bit variants on a 32 bit CPU will be slow due to the added complexity of performing 64 bit operations on a 32 bit CPU.

    On a 64 bit CPU SHA-224 and SHA-256 will be a little slower than the other variants. This is because due to only processing 32 bits at a time, they will have to perform more operations in order to make it through the same number of bytes. You do not get quite a doubling in speed from switching to a 64 bit variant because the 64 bit variants do have a larger number of rounds than the 32 bit variants. "
