I'm experiencing troubles when installing and updating dependencies via pacman, download speed is waaay too low like 30-40 kb/s. I've tried reflector and rank-mirors, I even moved mirrors from another machine where everything works well but nothing helped.
As far as I can tell it's not a slow internet connection problem, because when I download torrents the speed is good (up to 7 megabytes per second).
[pinkolik@acer-laptop ~]$ cat /etc/xdg/reflector/reflector.conf
# Reflector configuration file for the systemd service.
#
# Empty lines and lines beginning with "#" are ignored. All other lines should
# contain valid reflector command-line arguments. The lines are parsed with
# Python's shlex modules so standard shell syntax should work. All arguments are
# collected into a single argument list.
#
# See "reflector --help" for details.
# Recommended Options
# Set the output path where the mirrorlist will be saved (--save).
--save /etc/pacman.d/mirrorlist
# Select the transfer protocol (--protocol).
--protocol https
# Select the country (--country).
# Consult the list of available countries with "reflector --list-countries" and
# select the countries nearest to you or the ones that you trust. For example:
# --country France,Germany
# Use only the most recently synchronized mirrors (--latest).
--latest 5
# Sort the mirrors by synchronization time (--sort).
--sort age

Maybe you should uncomment the country option, and specify your country and a few close to you. Latest synchronized, doesn't mean they are close to you.
