ISTM you are the one throwing out unsubstantiated assertions without
data to back it up.  OP ran benchmark. showed hardware/configs, and
demonstrated result.  He was careful to hedge expectations and gave
rationale for his analysis methods.

If you think he's wrong, instead of picking on him why don't you run
some tests showing alternative results and publish them...leave off
the oracle results or use a pseudo-name or something.
