CentOS - May 2010 - Firefox slower on GMail since update to CentOS 5.5

Hello,

since I upgraded from CentOS x86_64 5.4 to 5.5, I noticed that Firefox
has become significantly slower on GMail (or Google Apps Mail).

The page becomes slow to scroll as soon as there are more than a few
mails in a conversation (like in a typical CentOS mailing list
thread).

Did anyone else notice that as well?
(I guess that I'm not the only GMail user around)
Could I have missed something / do something wrong?

More details:
- I did a fresh install from the 5.5 install DVD, keeping only the
home directories
- I'm using the Nvidia driver from elrepo (but I had the pb also with
the default driver)

Cheers,

Mathieu

I had somewhat similar problems. This is a shot in the dark, but do
you happen to have a Nvidia controller in your system? If so, you may
have been affected by this bug:

There is a workaround which solved the problem for me.

Hi Mathieu, I had the same problem with Firefox since I upgraded to 
CentOS 5.5.

I noticed very slow (almost unusable) Oracle Enterprise Manager 10g 
(Database Control, Grid Control and Application Server Control) and MS 
SharePoint pages, high X.org cpu usage and noisy fans activity.

I couldn't find anything about this on the web. Firefox downgrade didn't
help, but finaly I realized that I upgraded nvidia driver too - problem 
disapeared right after downgrade to nvidia driver 
NVIDIA-Linux-x86_64-180.22-pkg2.run. There are alse other versions 
between, but this one is the last one IMHO where PowerMizer works as 
expected (at least on my laptop).

My configuration is CentOS 5.5 x86_64 @ Dell Latitude D830, Nvidia 
Quadro NVS 140M.


Bye, Andrej
