sorry about the thread title, it isn't just firefox

First let me say I'm a newbie.
I've just installed SuSE 9.2. The problem I'm having is that web pages are loading extreemly slowly. I do have a broadband connection and the pages donot load at such a snails pace when I'm in windows on the same machine.
Any suggestions as to what I should do?

there are some tips which my friend has collected here

masand, this is not a firefox rpoblem, it happens in konqueror too...
its porbably a broken router not repsonding correctly to certain kernel tcp windows scaleing...

try this before tweaking firefox.....

ive seen quite a few posts like this.
i experianced this problem with the 2.6.7 and 2.6.8 kernel's

the answer was that the linux kernel started using a larger tcp window size. whihc in theory should boost network performace... however it became clear that some routers and firewall's didnt like the unusually yet standards compliant tcp window sizes.

and in later kernel's the window size was reset to normal.

trype the following command at a terminal and post what it says.

if you have the kernel i think you do, there are 2 solutions...

1) use a syscall to reset the tcp windows size to its normal value.
2) upgrade kernel.

i cant remember the exact command that carries out solution one... but its quite simple and on this forum. use the search function to find "slow internet tcp window size"

Solution 1 is given here..... http://www.linuxquestions.org/questi...cp+window+size

basically you need to do the following as root.

[code]
echo 0 > /proc/sys/net/ipv4/tcp_default_win_scale
echo "net.ipv4.tcp_default_win_scale = 0" >> /etc/sysctl.conf
[code]

better ?

Thats a neat trick masand, however, not a solution to my problem. Now firefox jumps to the web page but still downloads very slowly.

which *trick* did you try ?
if you treaked firefox's chche sizes etc etc etc, then thats whats to be expected.

i think the problem lies in the kernel... you forgot to post your uname -r. so i dont know.

sorry I was reffering to the firefox trick.
the uname -r :
2.6.8.24-default

good, i tried the given solution

looks like it is improving more

You may want to look at this as well - I had the same problem and the second I disabled IPv6 the problem went away...

Ditto...I had the same issue, and following the link above everything is absolutely fine now in terms of speed.

if u want to download, then i think u should try
d4x with flashgot plugin for firefox

From the above command I recieve: no such file or directory

Next, I can't figure out how to add the suggested line net.ipv4.tcp_default_win_scale = 0 to: /etc/sysctl.conf

I can't find those diredtories, I do have a directory named, /proc/sys/net/ipv4/ , however, no directory /etc/sysctl/ .

What am I doing wrong?

Should I just upgrade to a different kernel, if so, how do I do that?

go here

/proc/sys/net/ipv4/

and u might be havnf a file with some different name
like
tcp_windows_scaling

therer u can replace 1 by 0

and the reason for that is posted in the link

Okay, I did find the directory /proc/sys/net/ipv4/ so I entered the command etho O > /proc/sys/net/ipv4/tcp_window_scaling but I can't tell if it worked. Page downloads still are not faster.

I look in the /etc/ directory and look at sysctl.cong , there I find the following lines already there:

# Disable response to broadcasts.
# You don't want yourself becoming a Smurf amplifier.
net.ipv4.icmp_echo_ignore_broadcasts = 1
# enable route verification on all interfaces
net.ipv4.conf.all.rp_filter = 1
# enable ipV6 forwarding
#net.ipv6.conf.all.forwarding = 1
net.ipv4.tcp_default_win_scale = O
net.ipv4.tcp_default_win_scale = O


What should I do?
