> if you reduce latency from one second to a hundred milliseconds, could you celebrate that you've made it 10x faster

Yes you can, because speed has units of inverse time and latency has units of time. So it could be correct to say that cutting latency to 1/10 of its original value is equivalent to making it 10x the original speed - that's how inverses work.

Savings are not, to my knowledge, measured in units of inverse dollars.
