Only getting 7GiB/s on a Ryzen 7 1800X w/DDR4 3000. Zen 1 executes AVX2 instructions at half speed, but that doesn't account for all of the difference. I guess I need a new computer. To run FizzBuzz.

I ran this on a server with a 5950X (same CPU as this test was run on), but with 2666MHz memory (128GB) instead of 3600MHz memory (32GB) and I only got 41GB/s.

  Maybe because of taskset? Same cpu, no taskset, I'm getting 38-43GiB/s. With taskset, ~55GiB/s
