No Problem. Thanks very much for your very detailed reply,
which obviously took considerable time to write. While

Hello Doug,
sorry for the late reply, this week I was traveling.
First off, thank you for trying out MMTests; I admit the documentation is
somewhat incomplete. I'm going to give you an overview of how I run benchmarks
with MMTests and how do I print comparisons, hoping this can address your

Hi Giovanni,
Perhaps I should go off-list for this, not sure.

results as your "8x-SKYLAKE-UMA" on my test computer,
i7-2600K. Or that at least it was worth trying, just
to see. I couldn't find the same or similar test
on Phoronix, and my atte
