I just installed Fedora 25 on a Raspberry PI 3 with a 32GB class 10 card. Doing anything is painfully slow. Any command I type in the CLI takes a couple seconds to respond. A "dnf upgrade" took all night to complete. All the new rpms downloaded very fast, the upgrade/verify part is what took forever.
Last time I tried Fedora on a RPI was version 23 on an RPI2 and it was much faster. Is there any special configuration to be done for Fedora 25 so it speeds up? I also noticed that load average even when it is idle is over .5 and during the upgrade it went over 6.
