Hi David, this is as good as it goes I guess, the HAMILT was speed up by ~30%, but it is not so noticeable, because it actually scales much better with the thread number than the rest (so it is actually running much faster than the other parts at 4 threads, therefore further improvements are not as much visible), it is more relevant at the k- point parallel scenarios.
