One of them will throw a warning about "TotalDownload" which is deprecated as an option but it is fixed as enabled.

The default used to be 1, one repository updated at a time, one file/pkg downloaded at a time. There were a few hack-pkgs that provided this ability for pacman before, so Archers took notice and incorporated it to the new pacman.
