Re-asking a question I asked before in the other thread:

Also, what is the cycle count of ssse3/avx2 implementation for this
specific function on Haswell? It would be good to note that in the
respective patch so that we understand why the check was added.

You should be able to find this in the checkasm --bench --test=X numbers
for this relevant function.
