Firefox extremely slow page rendering in fedora 10

MarkRL · #1 3rd January 2009, 01:40 AM

Hey,
A while back maybe a year ago I decided to move to linux, but due to some unfortunate hardware issues I decided to dual boot until i could get things working perfectly. Fedora caught my eye and when I saw Fedora 10 was out I hoped the hardware issues had been resolved and decided to try and move over completely.

After installing and updating things everything looked good, with all my hardware running great. The only problem that I have now is with with firefox.

Firefox is just being a pain. It often takes 10 seconds to render a page, one which loads in less than 2 seconds in XP off the same network. I've been searching the forums and have tried several things but I cant seem to get anything really working satisfactory.

I'm up for trying anything and any advice I can get. This is one thing that would really be keeping me from moving permanently and I would love to get it fixed.

Unusually I did try opera but it too was extremely slow, more so that firefox and Im unsure if its a related but It may point to an issue other than with firefox itself.

If want any info or anything please ask, This is one problem I really want to fix.
Thanks in advance,
Mark

Are you using wireless network, if so, show:

Code:

ip addr
iwconfig

MarkRL · #4 3rd January 2009, 05:14 PM

Ya Demez one of the first things i tried was to disable IPv6, but it didnt speed anything up noticeably.

for ip addr

and for iwconfig

I never exactly thought that it could be a wireless problem but I suppose it could. Cheers

EDIT: Although it could be a wireless problem, I just realised that when downloading through firefox and yum the speed is fairly normal so Im not sure if its wireless.

has to be related to ipv6 im just wondering if things speed up if you disable NetworkManager an use the other network config

What card and video drivers are installed ? Also, what DNS servers are in

Code:

cat /etc/resolv.conf

MarkRL · #7 4th January 2009, 01:48 AM

My first idea was that it was ipv6 related as there was a lot of people talking about it but I did disable it and there was no real speed increase. But is there anything else I can do to check is this is the problem? And Demz, I disabled the networkmanager from services and didnt notice any significant result although Im not sure exactly if anything else was to be done here, so any advice is welcome.

In terms of graphics cards (which I suspected to be the problem for some time) I have a nVidia GeForce 8600M GT running off the standard drivers obtained from running
yum install kmod-nvidia.
Would getting the drivers from another source (nvidia perhaps) help?

The exact output of cat /etc/resolv.conf is shown below. Im not quite sure what to look for although the fact it says something may not be recognised doesnt look right..

# Generated by NetworkManager
domain Belkin
search Belkin
nameserver 27.0.0.1
nameserver 192.168.2.1
nameserver 212.113.0.3
# NOTE: the libc resolver may not support more than 3 nameservers.
# The nameservers listed below may not be recognized.
nameserver 212.113.0.4

Thanks for the quick responses, If i can get this fixed Im completely free from windows. And I like the sound of that!

Thy router is thy enemy

1: Search the howto for your fedora version and follow the steps to get proper video drivers It's in HowTo Section

2: Get rid of the items highlighted in red. Each one induces a delay and it's useless. The only valid nameservers are 212.x.x.x (Also, you could use those in my sig)

Code:

# Generated by NetworkManager
domain Belkin
search Belkin
nameserver 27.0.0.1
nameserver 192.168.2.1
nameserver 212.113.0.3
# NOTE: the libc resolver may not support more than 3 nameservers.
# The nameservers listed below may not be recognized.
nameserver 212.113.0.4

I was starting to think that it was the router or at least not firefox as I also tried swiftfox and the 3.2 pre-beta release of firefox and they all were slow. Bit coincidental if not related.

Just going to install proper drivers now, and by remove do you just mean delete the lines from /etc/resolv.conf?
or something more tricky.

MarkRL · #10 4th January 2009, 02:43 AM

Looks as though thats the problem!
Both firefox and opera are now operating at normal speeds, even a bit faster than their windows counterparts I'd say! Once again thanks very much to everyone, this was the last thing that was holding me back at all!

However it appears to reset to include the edited out lines each time I reboot so is there a more permanent way to remove the nameservers perhaps?

See System-Administration-Network

is a mistype

this line could get some delay to your resolver

localhost is 127.0.0.1

Nokia · #13 4th January 2009, 09:45 AM

Doesn't matter. His box isn't a DNS server.

MarkRL · #14 5th January 2009, 03:47 PM

Right, I may have messed things up for myself, not sure so I could do with some advice again!
For the first two times or so I just used nano to remove the useless nameservers from /etc/resolv.conf
but then i removed them and replaced them with only 212.x.x.x nameservers in System-Administration-Network . Since then newtorkmanager up in the panel just says my devices are unmanaged and I cant access connections at all. Is there anyway to reset it back to what it was, or to fix it in general?

EDIT: Right ignore that! got it working! just forget something small myself although Im still not certain how i will remove them exactly.

Vladi · #15 13th January 2009, 09:34 PM

I had the same issue. But this did the trick!! Thanks.
