firefox performance issue

zoran119 · 12-17-2008, 01:09 AM

hi everyone,

i tried to view the screen shots that are on http://linuxmint.com/ and it uses one of those fancy pop-up js image preview things.

my firefox is struggling to show it. 100% cpu usage and it takes about 7 seconds to move from one image to the other.

any idea on how to fix it?

Hmm, it works fine here, but then I have a very powerful machine. What version of FF are you using ?

zoran119 · 12-17-2008, 02:31 AM

Code:

$ firefox --version
Mozilla Firefox 2.0.0.18, Copyright (c) 1998 - 2008 mozilla.org
$ uname -a
Linux vulcan 2.6.21.5-smp #1 SMP Tue Jun 19 14:52:25 CDT 2007 i686 AMD Sempron(tm) Processor 3000+ AuthenticAMD GNU/Linux

I can confirm i have no issues with this website using slackware 12.2 and firefox version 3.04.

Have you tried FF 3.0 to see if it does this on there too ?

no change... still very slow... very slow... i'm starting to think it's the video card drivers. could this be the reason?

Code:

$ firefox --version
Mozilla Firefox 3.0.4, Copyright (c) 1998 - 2008 mozilla.org
$ glxinfo | grep rendering
libGL warning: 3D driver claims to not support visual 0x4b
direct rendering: Yes
$ glxgears
libGL warning: 3D driver claims to not support visual 0x4b
1245 frames in 5.0 seconds = 248.915 FPS
1257 frames in 5.0 seconds = 251.336 FPS
1257 frames in 5.0 seconds = 251.327 FPS
1257 frames in 5.0 seconds = 251.321 FPS
1257 frames in 5.0 seconds = 251.328 FPS

EDIT: Radeon 9600 with radeon driver, dual screens

Tried it under akregator, Opera, Konqueror and Firefox 2.0 and none of them has a 'performance problem' with it; takes a few seconds to load, and then it scrolls sideways as fast as you would expect.

zoran119 · 12-17-2008, 04:20 AM

there is no problem with the side scrolling... it's once i click on one of those screen shots to have a look at that the 'performance' goes down. i tried it in konqueror and it is much better (even tho it seems to render the page quite differently to firefox)

I have had the same problems in the past with FF2, Adding:

Code:

Option "AccelMethod" "XAA"
Option "XaaNoOffscreenPixmaps" "1"

to xorg.conf helped a lot.

I'm not sure if that could explain delay several seconds long in firefox. But IMO fps is pretty low, and scrolling on the page you mentioned isn't really smooth. Modern cards normally have above 2500 fps in glxgears. But this is for just one monitor (you mentioned dual-screen, and I have no idea how it can affect fps) You could try googling for "libGL warning: 3D driver claims to not support visual 0x4b
"

Firefox is a standard Slackware package. The packages at slacky.eu are non-stock or bleeding edge packages. To know when to update Firefox simply join the security mailing list at slackware.com. You'll be notified when there is a security update for Firefox and any other Slackware package.

ok. i was a bit confused because i'm still running 12.0 and the last firefox update is 2.0.0.18... but i now want to run firefox 3.

so if i just keep an eye out on the change log and get firefox updates from http://slackware.osuosl.org/slackware-12.2/ (12.2 package). is this ok?

Firefox is slow when I visit some sites with alot of flash animations, for example, movies.ign.com is ridiculous slow on my system, I dont think my hardware is the problem (Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz, 2GB RAM, GeForce 8500 GT, etc)

I tried those xorg.conf options from above and nothing happened.
