I wonder if it also varies somewhat by cpu - there might be some cases
where a slower cpu will perform relatively better compared to a
nominally faster cpu on a certain algorithm based on the cost of
different operations.

I think the ssh optimisations sound like an excellent idea - could I
suggest splitting it out onto a thread with a different subject (and
potentially different set of list
cc's) to get more attention and then push the result back into a
tech-install thread? :)
