[SOLVED] Pacman slow download speed

Hello everyone!

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).

How can I troubleshoot this?

Thanks!

Use reflector. Sometimes it happens

# reflector --latest 20 --fastest 5 --save /etc/pacman.d/mirrorlist

This one + pacman -Syy helped me! Thank you a lot!

Which countries are you including? I usually pick some neighbouring ones too

Show us your reflector conf and your mirrorlist.

Furthermore, check your mirror's status here

They seem to be synced

# Set the output path where the mirrorlist will be saved (--save).
--save /etc/pacman.d/mirrorlist

# Select the transfer protocol (--protocol).
--protocol https

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.

try doing pacman -Syy

it works for me, I have to do it every few months 🤷

I doubt it's only pacman. Try downloading something with wget for example. It should also be slow then.

g7s@lemmy.ml · 3 pts · 3y (1 reply)

It absolutely can be only pacman, if the mirrors chosen are on the other side of the planet.

mrmanager@lemmy.today · 1 pts · 3y

Sure but I just assume that's not the case... :) But let's see.

Maybe your BitTorrent software eats all the bandwidth so other networking programs shows bad performance?

Have you tried pacman without running your BitTorrent software?

Nah, I was only testing speed with torrents, right now pretty much everything is disabled
