> Thanks for the results. Does not look like the win is necessarily there, and even if so, it is unclear if it is justified by the computing power thrown at it.

I guess that somewhat depends on what is important to you, i.e. performance per cycle or wall time duration to complete task.

> That is to say, can you redo these while collecting cycle counts?

I'm not setup to do that and IIRC (like most things) it's not so trivial to do so on Windows. But as I mentioned above, it partly comes down to what is considered "good" performance.
