Very slow download speeds in Arch

dex · 2009-10-13 16:19:52

Hello,
I'm using Archlinux on a Macbook(Core Duo) with Windows and Macosx also installed.
The problem with my Arch installation is that the download/internet speed is really slow ( 240KB/s ) compared to win/macosx (and also other linux live distros like partedmagic) where i have download rates of 2.0MB/s.

I tried to change some settings like disabling ipv6, without success. I also tested the Archlive CD, where i also had slow download rates. So it seems to be some specific setting in arch limiting my network, any ideas what could be the problem?

Thanks,
dex

From the FAQ :

Q) Why is my internet so slow compared to other operating systems?
A) Is your network configured correctly? Have you double checked your /etc/rc.conf /etc/hosts and /etc/resolv.conf? Have a look at "Configure the System" in The Beginners_Guide.

You might want to visit the Configuring network wiki page too .

If the problem is still there , more information is needed for us to help you(wired or wireless, network card model and driver,....etc) . A Mac with dual core processor doesn't say much .

i checked my network settings (using dhcp, ip+dns from my isp) and tried disabling tcp window scaling, but that didn't work.

i'm using a wired connection, network card is a:
01:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 22)
using the 'sky2' module

# dmesg | grep sky2

ok .
Can you paste the output of "grep -i host /etc/rc.conf" and "cat /etc/hosts" ?

Did you disable ipv6 in firefox, too? If not, go to about:config and change network.dns.disableIPv6 to true.

@Nezmer:

[root@lappi ~]# grep -i host /etc/rc.conf
# HOSTNAME: Hostname of machine. Should also be put in /etc/hosts
HOSTNAME="lappi"

[root@lappi ~]# cat /etc/hosts
#
# /etc/hosts: static lookup table for host names
#

#<ip-address>   <hostname.domain.org>   <hostname>
127.0.0.1               localhost.localdomain   localhost

# End of file

i noticed the wrong entry in the hosts file and corrected it, now it looks like that, but no improvement in download rates:

[root@lappi ~]# cat /etc/hosts
#
# /etc/hosts: static lookup table for host names
#

#<ip-address>   <hostname.domain.org>   <hostname>
127.0.0.1               lappi.localdomain       lappi
# End of file

@MadTux:
i have slow download rates no matter what browser or download-manager i use, changing the setting in firefox made no difference.

Have a look at this http://wiki.archlinux.org/index.php/Beg … tc.2Fhosts i think your /etc/hosts file should look something like this

#
# /etc/hosts: static lookup table for host names
#
#<ip-address> <hostname.domain.org> <hostname>
127.0.0.1 localhost.localdomain localhost lappi
# End of file

@guzz46:
i tried your /etc/hosts file, but got no improvement

You might want to be sure your hostname.domain.org matches like guzz printed. To be sure, do your rc.conf hostname and /etc/hosts name match?

dex · 2009-10-15 07:31:39

i've set it up like guzz posted, according to the wiki my settings should be correct?

[root@lappi ~]# grep -i host /etc/rc.conf
# HOSTNAME: Hostname of machine. Should also be put in /etc/hosts
HOSTNAME="lappi"


[root@lappi ~]# cat /etc/hosts
#
# /etc/hosts: static lookup table for host names
#

#<ip-address>    <hostname.domain.org>    <hostname>
127.0.0.1        localhost.localdomain    localhost lappi

# End of file

your host settings look fine . I have no idea what's your problem . Maybe It's a regression in the driver. Maybe It's something else .

Googling gives me this page which has a suggestion to fix your problem from our Gentoo friends :
http://en.gentoo-wiki.com/wiki/Sky2

Google for "sky2 slow linux" for more pages that might be helpful .
