improved use of MovingMinMaxAvg<> for better performance

* tweaked options of MovingMinMaxAvg<> to have better performance with same results
* added timing results for the network vs stats collection so we can see if stats collection is really bogging down system
ah yes... we should punish who ever merged the PR that included this in the first place!

But yes.. but the rules of engagement, I should fix the coding standard violations in the code I touch.

I will update the PR shortly.
