 Posted: Sun May 07, 2006 2:27 pm Post subject: Firefox slowness |
 |
|
Due to the vast amount of work I am doing now at college I have been unable to visit gentoo forums very often.
I'm pretty sure this problem has been already discussed here.
I am running Gentoo on Pentium-4 3Ghz, 1024 GB RAM, 2 SATA (160+200 GB) drives. Primarily running KDE as the desktop environment.
My Mozilla Firefox is compiled with the following USE flags: ipv6 java mozdevelop xprint -debug -gnome -xinerama
The problem with Firefox is rendering of the pages. When I open some websites (especially forums using vBulletin, new AJAXy Yahoo Mail is another example) it takes quite a lot of time for the browser to render the pages - it stays non-responsive for a second or so before it displays the page in full, which is extremely annoying.
Could someone either advise me if there is a solution to this problem, or give me a link to another thread, where this has already been discussed.
Thanks |

| Any debugging output? (Run "firefox" in a terminal.) |

What's your graphics card? Are you using COMPOSITE?
I suggest using firefox-bin. I always found it to be faster than manually compiled firefox. |

What version of firefox are you running?
I had this problem with 1.5.0.1-r2 but it is was completely resolved when I upgraded to 1.5.0.3. |

No debugging output, version 1.5.0.2 (compiling 1.5.0.3 at the moment).
I am not using COMPOSITE extension, the graphics card is ATI X300 but the dri module fails to work with xorg so until my exams are over, I'm on VESA
The problem appeared quite a while ago - even when I used fglrx or dri module for xorg6. |

Compiled 1.5.0.3 now. No change  Still slow.
At college I have a machine similar to mine. It runs debian unstable, and still it's the same trouble with firefox.
Have no other people come across this? Do I just have a bad karma?  |

Actually, I've noticed this problem on Gentoo since Firefox 1.0.7. Since then, I've been using Opera devel (not in Portage), and have stuck to firefox on other distros and FreeBSD, where it is not so slow.

Yeah, it started about that time. Is anyone aware of what happened?
Would installing mozilla or seamonkey fix the prob? |

try
export MOZ_DISABLE_PANGO=1
and after that run firefox.

| mmmh, maybe it should try that too... firefox is awfully slow, especially at displaying some (complex ?) pages such as those which include many css styles (gentoo-wiki for instance)... for those pages, scrolling is hardly usable... |

Mine doesn't even have PANGO compiled in and exporting this variable doesn't seem to help |

Which version of firefox do you use?
1.5-series have been built with pango-support by default (in fact it could not be disabled at compile time) - the only possibility is exporting this variable.
well if this does not help, I don't really now - but I don't have such problems, probably try to upgrade all the dependacies, gtk+, pango, glib - if you don't have the latest versions installed.

WOW BOB WOW! 
export MOZ_DISABLE_PANGO=1 really did the trick for me. This should really come as a USE flag option so it be included in the /usr/bin/firefox Mozilla launcher script. Anyways that's where I put it. |

A full second??!?! You mean, a million nano-seconds???? Unacceptable! |

one second = 1 billion nano seconds (10e-9), and yes that is way too long! |

you can choose between:
a million microsecond
a billion nanosecond
but you can't mix the two  |

| Just throwing this out there, but is it possible that this firefox slowness could actually be a DNS lookup issue? Have you tested other browsers? |

Yep - DNS works fine. MOZ_DISABLE_PANGO=1 doesn't seem to make MUCH difference though.
I've recently used firefox on windows - no problems/slowness whatsoever! :-/ |

So do you mean that DNS works fine in other applications in Linux as well? You only mention Windows here...
Not to press the issue or anything, as I'm sure you know how to do adequate testing, but I've had many strange problems with slow DNS in Linux (where it would work fine in Windows). |

How about not using VESA. That's a recipe for fantastic slowness. The opensource drivers for the x300 now support EXA and COMPOSITE with decent performance. You can always turn off COMPOSITE and get even better 2d performance. Never use VESA unless you absolutely can't use any other driver (e.g., if there's no driver for your card, etc.). If you're still using Xorg 6.x, the open source drivers are pretty fast, but you can't use COMPOSITE as it is incredibly slow. |

you can put it in your /usr/bin/firefox script, but that gets overwritten if you re-emerge firefox
I imagine you could also put it in one of your bash files that gets executed when you login |

That worked for me too. Thanks. How did you come up with the solution BTW?
This definitely should be the default with a notice in emerge log now as 1.5 had been marked stable.
/etc/env.d/10mozilla looks like a good place to add the above variable. |
