IMHO, low priority io throttle has been just about horrible in every way since it was introduced.
You can tell when it was introduced if you google for things like "time machine got super slow for no reason" and see when they start occurring en masse.
It has a strong habit, even on 100% completely idle machines, of slowing down throughput by 10x.
