Hi,
I search and don`t see that there is topic about my problem yet and don`t know is this here... I`m using fresh FC3 reinstalled for week and updated, problem is that something like to eat my pc power and I found that it is firefox... New firefox when opened couple tabs (last 5) and all try to download some site was fulling my memory/processor, top of the "top": 19.0 10.1 2:10.66 firefox-bin 10.2 50.3 11:52.26 X and load start to fullfill: load average: 5.31, 3.43, 1.98
Last time load was go so high that something kill some process and pc freeze. Only reboot help... So I`m thinking what to do, I have all updated etc. Start to think to compile maybe by my self ff. Don`t know what to do... Pc is year old Toshiba Satellite with p4 and 256ram.

Just wondering: Do you have a bunch of flashy flash animations open? Flash tend to eat cpu for breakfast...

I have a similar problem with no flash (don't even have it installed) where for some sites firefox cpu usage will go through the roof. The site I find this happens the most often is actually the Fedora downloads page where you have a listing for the entire distro seems to just kill firefox but if you go to a mirror its OK rather annoying since I'm often behind a firewall with no ftp access.
(eg http://download.fedora.redhat.com/pub/fedora/linux/core/3/i386/os/Fedora/RPM... )

This is caused by the large amount of content being rendered in a <pre>. If we turn on IndexOptions HTMLTable, we can probably get much better performance out of the browser here. Even older browsers such as lynx, w3m, links, etc handle tables fine, AFAIK.
I just quickly hacked together a script and converted the HTML to use tables. The difference is actually very noticable:
http://people.redhat.com/caillon/ftp-current.html vs. http://people.redhat.com/caillon/ftp-tables.html
My script wasn't perfect, so it isn't as pretty as it could have been I guess, but you get the idea.

Well, the tables version is much more readable and indeed is much quicker. Maybe now it is possible to list the full package names, instead of the cut off versions like "Glide3-devel-20010520-33.i386.rpm" instead of "Glide3-devel-20010520-33.i386..>"

What if we used repoview (http://linux.duke.edu/projects/repoview) for that index. Just like we're using in fedora extras: http://download.fedora.redhat.com/pub/fedora/linux/extras/3/i386/repodata/
How does that render for you?

Fine. Quite quick although its list of packages is much smaller.. Can it also show size and date/time of each package?

I redid the test and also ran them on mozilla. On both the current version takes along time, the tables version is quicker. But mozilla is quicker than firefox! (gkrellm cpu bar shows 100% cpu while page is loading, and the bars for mozilla are much smaller than for firefox).

Still Firefox from Fedora Core 3 compared to mozilla nightly downloaded from mozilla.org is about 2x slower loading this page:
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b2) Gecko/20050326 - about 9 seconds
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050323 Firefox/1.0.2 Fedora/1.0.2-1.3.1 - about 19 seconds
Is such a difference expected?
Am I comparing apples to oranges (very recent nightly build vs. stable release/mozilla vs. firfox)?

Compiling yourself probably won't help much to alleviate the problem since we already do optimize it quite a bit. However, if you care to do some debugging and profiling work, and can quantify a specific area of performance hit, and file a bug (and dare I say provide a patch?) that would be great. See e.g. the docs at http://lxr.mozilla.org/mozilla/source/tools/jprof/README.html or you can use the profiler of your choice.
At the very least, do try and figure out what specific webpage is causing the performance hit and if you can narrow it down further to which specific piece of the page that is even better, and then make sure a bug is filed on it.
And finally, the suggestion you probably don't want to hear: more RAM is probably a good option especially since you will likely get a good bang for the buck here. You're running at the minimum recommended amount for an FC3 graphical install, and keeping several large, image/animation heavy, etc. web pages in memory will almost certainly cause you pain. I bet that an upgrade to even 512MB will give you a substantial benefit, even outside of the browser space.

Attached is a testcase that shows high cpu usage for both firefox and mozilla. It contains a few animated gifs. I resize my browser so the bottom part of the page, including the animated gif in it, is outside the window. There are still 4 instances of the same gif visable. CPU usage in this case is just a few %.
Now when I scroll the bottom part into view so that the 5th instance of the gif becomes visible, cpu usage rises to 30% or 40%!
If other people can reproduce this I can file a bugzilla...

this is cpu cache effects: 4 gifs at XxY rendered resolution fit ok in data caches but 5th one spills. perhaps konqueror uses less mem and thus it can fit 5 and not 6, or it already does not fit 4 and it then feels equally slow with 4 and 5.

That could explain it perhaps. When I remove the gifs from the top part one by one the extra cpu usage when getting the bottom part in view is getting less. But opening mozilla and konquere at the same time, konqueror showing all gifs and mozilla with the bottom part hidden show no extra cpu usage. Again moving the bottom part in view in mozilla (so I see all animations in both mozilla and konqueror at the same time) gives a sudden increase in cpu usage.
I also created simple html page with increasing numbers of this animated gif and even with 20 of them in view cpu usages stays practically 0%!
I think there must be something more...
