>I use every day both SHA-256 and BLAKE3. BLAKE3 is faster only because it is computed by multiple threads using all available CPU cores. When restricted to a single thread, it is slower on CPUs with fast hardware SHA-256. That's not actually my experience. Last I tested, BLAKE3 was about twice as fast, single-threaded, as SHA256 on a Zen 3 CPU, which has the extensions. Lower down in the thread someone else did a comparison, and came out with a similar result.
