Uses stress-ng for benchmarking, even though the stress-ng documentation says it is not suitable for benchmarking. It was written to max out one component until it burns. Using a real app, like Memcached or Postgres would show more realistic numbers, closer to what people use in production. The difference is not major, 50% utilization is closer to 80% in real load, but it breaks down faster. Stress-ng is nicely linear until 100%, memcached will have a hockey stick curve at the end.
