How to Speed Up DNF Package Manager on Fedora 38 Workstation | Fedora 37 | Fedora 36 & Based - This guide is officially tested in Fedora, however it should work in all RHEL-based systems that uses DNF as their default package manager. We can increase the download speed while installing packages using the DNF package manager by increasing the maximum number of simultaneous package downloads.

Add the following line to enable DNF parallel downloads:
max_parallel_downloads=10
fastestmirror=True
Press CTRL+O followed by CTRL+X to save the file and exit.
Now you can see a noticeable difference when installing and updating packages with DNF in Fedora 37 or Fedora 38 Workstation Machines.
