New subject: [Wlug] Redhat GUI performance

May 9, 2003


      Some of this may also be related to the OS scheduler and VM configuration of the
kernel - both of which have been improved in the new 2.5/2.6 kernel. The new
shceduler is preemptive and does a better job of giving interactive processes a
higher priority which makes the box "feel" faster.  It is because of this feel,
that I actually run a 2.2 kernel on my desktop/workstation since it feels faster
than a 2.4 kernel (but does not support as much hardware which I can run 2.5 for
if I need to).
...
I've notice that when going from redhat 7.x to 8 or 9 you need a 
minimum of 256M RAM.   with 128M and running gnome there is way too 
much swap space in use.
Gnome and KDE are very bulky GUI's..   twm or blackbox are the slimest 
and fastest.    A friend of mine runs  gentoo linux and it seems very 
fast compared to redhat on the same box.
type the "free" command at the prompt and see your memory usage  also 
"ps aumx" to see process memory usage.
I would reccomend spending the roughly $40 to get a 256M upgrade for
your box.  More RAM almost always helps.  The os can keep more things 
in memory and give you a faster response.  I use 512M myself.
hope this helps

I have a general question about Linux performance...
I am running Redhat 8.0 on a Dell 400MHz, 128MB system (OptiPlex) with an
8MB ATI Rage Pro Video card.  I have a fairly basic workstation installation, 
with
SSHd, ftpd, telnetd, apached, and a couple other services running.  Gnome 
seems
to take forever to open windows/applications.  It can be on the order of 10 
seconds
to a minute for some applications to come up.  (Mozilla is one of the worst, 
even 
to just bring up a local file as the home page for the browser)
Is Gnome just a very slow GUI, or is there something that I can do to speed up 
my
system??
I know of several (5-6) people who have installed RedHat 7.2...8.0 on Dell and 
Sony
systems (all CPU are 866MHz+) with Gnome or KDE and the performance has been
very slow in the GUI.  Even with a higher end 1.5GHz CPU/512MB RAM system.
Is there a Linux distribution that has a standard GUI that is very responsive?  
Is Redhat
just too bulky to run quickly, or do I need to download a better GUI for 
Redhat?
With Windows2000, this system was very responsive, and the other people I know 
about are running XP, which is so much faster that they run XP most of the 
time now.
Thanks,
jeff

The hardest thing is to disguise your feelings when you put a lot of
relatives on the train for home.
