BLAKE3 keeping up with dedicated SHA CPU instructions (i.e SHA-NI) is
impressive.
I would assume that that's the AVX2 implementation (my CPU can't
AVX512), which makes it less impressive.
ARM is getting more and more common, and I don't think ARM has SHA
instructions (yet?) tho.
The ARM architecture has them, but PHP does not yet make use of them.
This is mainly due to me being unable to test the integration, due to
lacking an appropriate system. libcperciva where I've taken the SHA-NI
implementation from also includes the ARM implementation and I checked
with the author regarding the necessary attribution as part of the x64
SHA-NI PR:
https://github.com/php/php-src/pull/15152#issuecomment-2256476578.
As for the RFC itself: I suggest to already add the (closed) voting
doodle to the proposed voting choices section. The way the section is
currently worded doesn't make sense, because it implies two distinct
votes.
like this I guess:
Yes. Ideally mention above that it requires a "2/3 majority" (as with
any other RFC, but good to spell it out explicitly).
