Thanks everyone.

The initial benchmarks are kind of flat when using 3.8 GHz as the
frequency. I think the problem is, we are not working the machine hard
enough so the cpu's are reluctant to move from a low energy state.

For us, the benchmarks are boring vectorized algorithms. They are not
multi-core or computationally intense like mathematical modeling.
