This question suggests it wants to know the exact, tactical decisions. As much as I would like to share those tactics in great detail because it's fascinating and readers of this question would find it interesting/valuable, I'm legally bound to a certain amount of confidentiality so I'll only go as detailed as I'm legally able to. That basically means I won't share numbers and I won't comment on things that aren't directly discernable to the general public. Also, the list of optimizations is too long for anyone to remember. I also didn't work on the majority of those optimizations directly but tended to learn about them via close proximity to the people solving the problem they were assigned to solve.
