The firefox on my fully updated Fedora Core 4 box renders many larger pages very slowly. During the page rendering, Firefox "hangs" completely. A good test page is:
http://scragz.com/tech/mozilla/test-rendering-time.php
Rendering the scragz page, and others, on the same hardware and OS, various other browsers are over 4 times faster, including Firefox for windows:
Linux Firefox 1.06 42.23 Linux Konqueror 3.4.2-0.fc4.1 13.27 Linux Opera 8.02 build 1272 7.08 Windows (via VMWare) Firefox 1.06 8.18 Windows (via VMWare) IE 6 7.12
All of the above times are without any extensions *or* plugins installed (in fact, with Greasemonkey installed, Linux Firefox took over 100 seconds to render).
Running an strace on the Firefox process while loading occurred shows a lot of time being spent in brk() calls (usually one brk call was over 20s). Here is output from "vmstat 5" while the page rendering is occurring:

So swapping is not an issue. Lots of memory is available if cache is included. Not much disk activity is happening, but the CPU is getting hammered.
This was also tested using a completely new profile (no ~/.mozilla directory present), with the same result.
Can anyone else duplicate these results? Does anybody have any other debugging/setup/configuration suggestions?

Maybe you could try comparing Firefox from mozilla.org with the one from Redhat? Might help pin the problem down and let us know who to report it to.
Btw, I get about 3.5 seconds for that test, with Firefox 1.0.4 from Redhat on a fully updated FC2. That's on an Athlon XP 3200.

Good idea. Results below. I also tried Mozilla (from Fedora) and found its speed in the desired ballpark:
FC4 Mozilla 1.7.10 11.46 Mozilla Firefox 1.0.6 on FC4 8.19
I installed Firefox from mozilla.org and immediately recognized that it felt faster than the Fedora one. The test page time bears that out.
This is also a good confirmation that the problem is not specific to my profile, as the mozilla.org Firefox is using the same ~/.mozilla/firefox profile as the Fedora version.
Btw, I get about 3.5 seconds for that test, with Firefox 1.0.4 from Redhat on a fully updated FC2. That's on an Athlon XP 3200.
Since this test seems to be CPU bound, your 3.5 seconds vs. my 8.19 from the mozilla.org Firefox seem to be consistent given my computer's 1500 MHz (Intel Xeon) vs. your 3200 clock speed.
I will add this information to the bug report (https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=166449).

Tom

The reports so far seem to be pretty consistent that people who are using 1.0.4 have reasonable render times. People who are using 1.0.6 from Fedora have horrible render times.
As for hardware, I'm not sure how relevant it is given that almost every other browser (including Firefox on Windows via VMWare AND Firefox downloaded from mozilla.org) running on the same hardware performs at least 4 times better than the Firefox from Fedora Core. HOWEVER, here goes anyway:
Video : Nvidia GEForce 5900 XT 128MB Nvidia driver version 1.0-7664 (I should update this) acceleration enabled according to Xorg.0.log res 1600x1200
CPU : Intel Xeon 1500 Mhz (1-cpu)
RAM : 2 GB RDRAM
MB : Dell board with Intel 860 PCI/AGP chipset
I know I need to upgrade but 40-50+ seconds to render a page? No way :-)

It's not just Core 4's firefox. The firefox update for core 3 (firefox-1.0.6-1.1.fc3) behaves similarly - taking more than twice as long as mozilla (mozilla-1.7.10-1.3.1) to render that page.
I normally use good old Mozilla anyway, but ...

Well, this is an interesting data point: Fedora Core 4 x86_64 on Athlon 64 2.0 GHz (3200+) firefox-1.0.6-1.1.fc4.i386 (so it's 32-bit firefox) render time ~7 or 8 sec
For comparison, a 64-bit browser: mozilla-1.7.10-1.5.1.x86_64 render time ~3 to ~5 sec

I'm using Firefox 1.0.6 on FC3 on a 1.2 GHz Athlon. My render time is about 9.1 seconds. ____________________________________________________________________ TonyN.:' mailto:tonynelson@georgeanelson.com ' http://www.georgeanelson.com/

There are a whole bunch of things you can do with configuring Firefox
In your browser, do an about:config
There are an interminable list of settings for you to play with. Double-click on a setting to change it. I direct your attention to the setting called: browser.turbo.enabled Set this to TRUE.
These also look interesting. Check your values for these: network.http.pipelining = TRUE network.http.pipelining.maxrequests = 20 network.http.proxy.pipelining = TRUE
Good luck

If it says "turbo" it must be good right? :-) According to this page:
http://kb.mozillazine.org/Firefox_:_FAQs_:_About:config_Entries#Browser..2A
this entry was deprecated (and had nothing to do with render times even when it wasn't).
These also look interesting. Check your values for these: network.http.pipelining = TRUE network.http.pipelining.maxrequests = 20 network.http.proxy.pipelining = TRUE
Thanks, I've tuned these already. My download times are fine -- its the render time that is killing me.

I get subsecond rendering times in elinks <grin>. Of course the page is not so attractive.
Linux Firefox 1.06 13.75 seconds. Linux Konq 7.34 seconds.
Konqueror is definitely improving.

Is there any documentation on this? - I noticed that konqueror uses cache much more than firefox, yet didn't guess what to do in about:config.
