Recently the download speeds of Chaotic-AUR (our repo) were pretty bad for a lot of people. This has a simple cause: Many people wont ever change the default order of Chaotics mirrorlist since it is unaffected by Reflector (the Arch mirrorlist GUI) which results in everyone downloading from the same server. So lets find out how to get better speeds by using another mirror! :)
We are going to open the mirrorlist using micro - superuser needed:
sudo micro /etc/pacman.d/chaotic-mirrorlist
Then comment out all mirrors in front of the one you want to use (your best bet is to take one next to you). Then finish by refreshing the database using the new mirror.
sudo pacman -Sy
There is also an Asciicast which shows the process.
