This is simply not true, of course it isn't entirely linear, but for big downloads you actually get pretty close to the full benefit of the speed, when the servers can handle it.
When the speed goes up, latency also goes down, making response times faster too.
Sounds a lot like your Fedora update is single threaded, which is a huge limitation. I start updates manually and monitor the whole process, and the whole process is finished in a couple of minutes for a big update. A single package can be literally less than 5 seconds for download, integrity check and installation. Firefox is among the most frequent single package updates, and that generally takes 5-6 seconds.
What is not true?
Do the math yourself, it's only grade school level:
A download takes 100 minutes at 10Mbit. How long does it take at 20Mbit and how many minutes are saved?
The same download takes 2 minutes at 500Mbit. How long does it take at 1000Mbit and how many minutes are saved?
This calculation doesn't even take into consideration that most servers don't allow for gigabit downloads and that most wifi connections also don't allow for gigabit.
