pearOS ranks pacman mirrors by real download speed automatically, but you can re-rank them manually if downloads feel slow.

Easiest fix: open the pearOS Welcome app and click Update Mirrorlist.

Manual fix with reflector (the tool pearOS ships as pearos-reflector, renamed so it installs alongside Manjaro's pacman-mirrors):

sudo reflector --country YourCountry --age 12 --protocol https --sort rate --save /etc/pacman.d/mirrorlist
sudo pacman -Syyu

Replace YourCountry with your country's name (e.g. Germany, France), or drop that flag entirely to rank against the fastest mirrors worldwide.
