That's more an apt thing, dnf can use delta rpms with parallel downloads and automatically cleans unused packages. I'm not sure how well it cleans the cache though. On my fast home connection dnf is way faster than apt to update my laptop unless it's a really small update, then apt is faster because it refreshes the repos quicker. I think there are alternatives to apt that can do parallel downloads and delta as well.
