Fastestmirror and deltarpm are perhaps the best features of Fedora, but they are not available by default on the Fedora 32 workstation. To enable these fastestmirror and deltarpm, open a terminal window and do the following:
$ sudo vi /etc/dnf/dnf.conf <enter>
Add the following two lines to the end of the file
Once the above has been done, whenever an update is triggered, dnf will look for the fastest mirror and then download deltas of the rpm files that have changed instead of entire rpm files, saving time.
