pacman -- falling download speed

Hey,

i have a weird speed problem while pacman downloads packages.
The download speed in few seconds falls down near ~5 K/s.

-- i'm using my own mirror with high bandwith connection. With wget i can download the packages by 2.5 M/s, scp has almost the same speed.
-- i have tried with other, external mirror from the official mirrorlist, it's the same.
-- there are no errors in the tcpdump.

What can be the reason of this pacman specific extreme slowness?

Re: pacman -- falling download speed

A relatively long shot, but do you have the ipv6 kernel functionality enabled? If you have and aren't using an ipv6 link; try disabling it.

Burninate!

Thank you for the tip. I tried to start by kernel parameter

ipv6.disable = 1

but there is no change.

If wget works fine, you should try it for downloads in pacman by setting XferCommand to use wget in pacman.conf.

There might already be an entry for wget, just uncomment it:

XferCommand = /usr/bin/wget --passive-ftp -c -O %o %u
