Because my computer has 16 cores.
Try:

make -j
This will not make a difference for the generated code. It only affects how many parallel jobs make will start.
profile-build
I tried this and it speeds up both the AVX2 and the AVX-512 builds about the same amount, so there is still no speedup for AVX-512 compared to AVX2.

Apple silicon does not support AVX-512, which is what this thread is about.
