Im currently dual booting between Slackware 9.1 and Windows XP Home. I have been noticing lately that when I am on Slackware and browsing the internet, it is going VERY slow compared to when I browse the web on Windows. I have a cable modem, and under windows it loads websites almost instantly. On Slackware, it takes 30-45 seconds, maybe even several minutes to load a website. Now, I have done alot of testing, and I know that it is a problem with my machine and not the remote websites Im trying to connect to. I have tried connecting to a list of sites on Slackware, and then the same list with Windows, and the connection speeds on Windows were ridiculously faster. I am wondering if anyone could maybe suggest some settings that might be causing this lack of performance.

Also, as a side note... download speeds on Slackware are very good. I have been downloading alot of software lately and I can consistantly break 350mbps downloading files. However, even while Im downloading this fast, other websites load very slowly.

That may be a problem with DNS lookups, or
firewall rules ... hard to say from your description,
and without further background info.


Cheers,
Tink

Well what other kind of info would you guys need? I am very new to linux so Im not sure what this problem really involves. Im currently running the Firestarter firewall. I can find out any other info though if someone can just tell me what they need to know.

I have continued to do some research, and found out that there might be a problem with my DNS cache (I think thats what it was...). Anyway, it said to dig a site once, then dig it again and your response time should be significantly better the second time. Unfortunately, mine was not. Here are my results from digging www.google.com 3 times:

As you can see, my query time was not only horrible each time, but it didnt improve either. So, next it said to check and see if I was getting any errors when I ran ifconfig, and here is the output from that:

eth0 Link encap:Ethernet HWaddr <EDITED OUT>

Now, I may not be a linux guru, but the line:

RX packets:71755 errors:5279 dropped:0 overruns:0 frame:

contains 5279 errors. Thats probably not a good thing Im guessing. So maybe this might be my problem?

Anyone?

It's not a good thing, but it's not necessarily
the reason for the performance. How about
double-checking /etc/resolv.conf and make
sure the name-servers are correct. And see
whether your firewall blocks anything DNS
related.

I have the same problem. I need minutes to load a web page.

ping google.com : 107 ms
dig google.com : 12 ms
http://www.google.com in Firebird : more than a minute

The same hardware gave normal results under Mdk 9.1 with kernel 2.4

I am behind a NAT router, but so is my other PC, and that one does not have any problem (running XP)

If I bypass the router by plugging into the modem, it does not get better.

My ifconfig says :

[root@linolivier nwn]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:08:A1:2D:9C:8A
inet addr:192.168.0.3 Bcast:192.168.0.255 Mask:255.255.255.0

My /etc/resolv.conf says :

nameserver 194.19.194.9
nameserver 194.255.56.78
nameserver 212.66.1.1


What more information should I provide ?

this helped me

/etc/modprobe.conf
add the following command

alias net-pf-10 off

It seems to have helped some.

But I still have a big difference if I ping google.com or the direct IP address : so I still have a resolution problem somewhere...
