Hi,
I have my laptop installed with Debian for two years. It's been working
fine, although some problems happened and got fixed. (Now is Lenny,
2.6.24, Xfce4). The system has been very stable, but just with
performance issues now. The time to start the system is OK (usually
about 22secs in bootchart). The issue is with GUI applications. When I
entered xfce4, it takes about 14secs for everything is ready, and when
I open the Firefox (or Mozilla product), it always takes about 15secs
to 20secs to be ready.
It looks as if you have the
same problem as I encountered with Firefox: due to some problem with
IPv6 handling
Firefox becomes slow. I'll pass on two remidies which I received.
1) rimaya sent me the following tip, which worked:
As root you enter on a console
echo "blacklist ipv6" >> /etc/modprobe.d/blacklist
and restart your PC.
2) In Firefox enter as address
about:config
You will see a very long list of variable set for Firefox.
Find the entry
network.dns.disableIPv6
If it is set to "false" click on it twice to change it to "true".
Close the window and Firefox.
Modification 1) was sufficient for me. I do not know whether mod 2)
alone is sufficient;
I did both.
The system may be getting slower because I have been configuring and
installing new staff on it. I just wonder if there is any way to tune
on it, or maybe somewhere many caches need to be cleaned up?
I also used ext3 (journal) as my file system when I first time
installed the system. This may be another factor of the issue. For sake
of safety, I don't know how to remove the journal features without
damaging my system with minimum risks. Any expertise can give advice
and guidance on this if it can improve the performance a lot?
Thanks,
Michael.
HTH.
