On: Reasons to Prefer Blake3 over Sha256

Not even close. CRC32 can easily run at >50GB/s single thread on this i7-12700K CPU (VPCLMULQDQ implementation). The BLAKE3 page claims around 7GB/s single thread. Fudging the figures a bit to cater to CPU differences, BLAKE3 is still a far cry from CRC32.

You're referring to the implementation that was on HN a month or two ago?

There's nothing wrong with that, it's a fair comparison, but I'm talking about the existing common implementations.
