Actually, I think sha-256 is possibly faster than the sha1dc variant that Git currently uses.

I just sent a patch series to the list that enables sha1dc to be accelerated on modern CPU architectures to close to normal SHA1 speeds, but since it was ported from a Rust project by an agent, it will never be applied.
