slow browser on a new install

darkflow · 05-11-2014, 11:33 AM

Hello,

New 14.1 install and both konqueror and firefox a slow at loading pages. Few years ago I had the sma eproblem, but now I cannot remeber what I've done to fix it.

Tried disabling IPv6 on the firefox, but didn't make any difference. How can I analyse what causes browsers/internet to be so slow?

thank you

The problem you describe is often due to incorrect DNS settings in /etc/resolv.conf
To help more please describe how you connect to the internet e.g. is this a home computer connected to a modem/router?
Are you using a connection manager (NetworkManager or wicd) or making settings in /etc/rc.d/rc.inet1.conf?

Perhaps this SlackDocs page will help. http://docs.slackware.com/slackware:...e_your_network

As default, on Slackware, the BIND daemon is configured for DNS caching. This is right what can help you.

Just do:

Code:

chmod +x /etc/rc.d/rc.bind

/etc/rc.d/rc.bind start

You should see the difference, specially on Konqueror.

Lots of threads on disabling IPv6 in this forum - one recent one. I would suggest disabling it globally and see if that helps.

Your next step should be to open a terminal and try pinging the hostnames of the slow websites.

Then ping the IPv4 addresses of those hosts and look for any significant difference. If pinging IP addresses is fast and pinging the hostname is much slower, then the problem lies somewhere in DNS resolution.

Then ping your access point/router.

@allend

home computer connected to the router

using /etc/rc.d/rc.inet1.conf

@Darth Vader

i do not have the /etc/rc.d/rc.bind file in the directory.

@cynwolf

pinging IP addresses and hostnames is the same - 121/122 ms

Please post the output of the following commands run as root in a terminal window.

Code:

grep -v "^#\|^[[:space:]]" /etc/rc.d/rc.inet1.conf
route
cat /etc/resolv.conf

All those settings look perfectly OK, so I do not think the problem is in your Slackware setup. I suggest looking at the DNS server settings in your router. As a test, try changing the primary DNS server to a public DNS service like that provided by Google at 8.8.8.8 rather than that supplied by your ISP.

allend, I will take a look at the DNS server settings in my router, but in windows browsing is not slow, no problems there - I use Firefox in windows as well.

Also, I installed BIND and it is a fair bit faster now, but still not as fast as in windows. Why does BIND make it faster and is there a faster alternative?

cynwulf · 05-25-2014, 08:33 AM

BIND is doing local DNS cacheing so if that is improving things a lot, then DNS configuration may still be at the root of your problems, if it's just improving things a little, as it should, then DNS may not be the issue.

Your nameserver in /etc/resolv.conf points to the gateway, so if the gateway is configured properly and other workstations don't have DNS problems, then that also points to this not being DNS related.

If you haven't diabled IPv6 globally, then try that first. I don't see any problems with IPv6 being left enabled these days, but then I'm not you nor connecting to your ISP. However, I still disable it out of habit until such a time as my ISP implements it...

Use this method:

https://www.linuxquestions.org/quest...8/#post5168803

Find the "append" line at the top of /etc/lilo.conf

e.g. if your append line looks like this:

Code:

append=" vt.default_utf8=1"

add this part

Code:

append="ipv6.disable=1 vt.default_utf8=1"

Run lilo and reboot

If that makes no difference then I'd start to suspect something with the network hardware. Post the output:

Code:

$ /sbin/lspci -k|egrep -iA5 'ether|netw'
