we traced the issue to a 15-year-old Git function with O(N²) complexity and fixed it with an algorithmic change, reducing backup times exponentially.

I feel like there is something wrong with this sentence.

Seem ok to me, both in grammar and what it's saying about the change. O(N²) to O(N) would be an exponential drop (2 down to 1, in fact).

An "exponential drop" would be a drop that follow an exponential curve, but this doesn't. What you mean is a "drop in the exponent", which however doesn't sound as nice.

It's at least misleading 😛

But I have to agree that for any non-math people this would convey the right idea, whereas "quadratic improvement" would probably not mean anything 🤷
