I've been using various versions of Fedora on my laptop
for some time now and recently I upgraded to fc5.
I always used to have a firefox installed in /usr/local/firefox
and it was the non-RPM package downloaded from the Firefox
people (bypassing RedHat). After the upgrade, fc5 put their
version of firefox onto my system and I started using it but
recently have been noticing high CPU usage. I'm not sure if it
just started happening recently or if it was always happening
and I just recently noticed. At any rate, I'm sure things moved
a lot snappier before the upgrade.
Then I tried deleting my local version and the RedHat package
version and using yum to fetch the latest firefox RPM which is
firefox-1.5.0.2-1.2.fc5 and I believe that I might have a
relatively clean start after removing the old packages and reinstalling.
Still it uses heaps of CPU, even for simple operations like loading
a page or scrolling up and down on the screen, or flipping between
menus! It still happens when I turn off both Java and Javascript,
even bringing up the edit/preferences pop-up takes a good 6
seconds on a 2.5G Celeron machine (I'm sure it never used to be
so bad).
Have I visited a nasty web page that hax0red some junkware into my
system or is this version of firefox getting bloated like mozilla
did ? Has anyone else seen this sort of thing happening ?
Also, gedit takes about 5 to 6 seconds of 100% CPU activity,
check the results of "vmstat 1" :

I'll point out that gedit never has come up all that quickly but
it's slower now than it used be (by a noticable amount) and it is
a fairly basic text editor so what can it be doing with all that CPU?
Just as a comparison, bringing up emacs (the most bloated beast in the
world) uses less CPU than gedit...

What going wrong with my system ?
It always used to be so good, should I go back a few versions or maybe
reinstall fc5 from a clean start...
The kernel is Linux version 2.6.15-1.2054_FC5 which is the stock standard fc5
kernel.
This 2.6.15-1.2054_FC5 is really a 2.6.16 release candidate. So, firstly
upgrade to 2.6.16-2096_FC5.
Then ensure, that in your /etc/yum.repos.d/ only the following files are
enabled:
1. fedora-core.repo
2. fedora-extras.repo
3. fedora-updates.repo
To upgrade, I'd do,
#yum -y update kernel
Then, reboot and check manually the output of,
#yum list
paying particular attention to thunderbird installations.
Then, do a
#yum upgrade
I'd also move the directory ".thunderbird" to say ".thunderbird.orig"
and do a "#rpm -e thunderbird" and a "yum -y install thunderbird".
Then test.
Hope this helps.
