KDE and GNOME very slow
dear mates
recently i assembled on 1.8 Ghz and installed Redhat Linux 9.0
it contains 256 MB DDRAM, and 1.0 GB swap space,
what is more annoying me is, it is very slow when i will be opening eclipse or jboss,
when i am trying to find out where it goes wrong using TOP command, it shows 147 MB usage of X,
how to solve this

The only ways to solve this that I know are to rewrite X from the ground up.
X eats memory. Right now on my box:
1323 root 10 -5 288M 29M 268M S < 0.1 5.8 0:38 X
Thats right 288 MEGS OF MEMORY JUST FOR X!!!!
KDE and Gnome are the slowest options for a gui. If you want something snappier try fluxbox (fluxbox.org) or enlightenment. Or buy more memory, or both.

Just to add to that list, try ICEWM. I installed it tonight and it is WICKED fast :-)
Also I'm curious what did you use to get that output (I'm guessing some form of "ps")? Because when looking at "top" X on my machine appears to only be using about 32MB of memory; unless I'm just totally reading the darn thing wrong (total possibility since I'm a newbie).

You can also try out xfce ( www.xfce.org). It totally blows your mind. |

"appears to only be using about 32MB of memory"
Could be that Im reading it wrong. 288 was the SIZE column in top.
From the top man page:
SIZE The size of the task's code plus data plus stack space, in kilobytes, is shown here.

288KB is actually small then. 288KB = 294,912Bytes not 288MB. I just ran top again and my SIZE for X is 30468. Which I understand to be 31,199,232Bytes (i.e. 32MB).

let's see something interesting on a 256MB system:
ps -aux
a few minutes ago:
8.5% 21940k /usr/X11R6/bin/X
2.3% 5936k [xfs]
7.8% 20562k xf*
when I launch ksim:
x use 2MB more ram
ksim use 18023k (7.0%)
kdeinit: * use 54582k (21%)
When I launch a kde session, 170MB lost immediately. 
Another problem is that the session may start up dirty. kde may restore an out of control application that would eat up resources.

It was listed as "288M" ... megabytes. Top doesnt show anything for sizes in kilobytes. Right now:
1656 root 10 -5 289M 30M 268M S < 0.9 6.0 1:27 X
289M total memory used. 30M physical memory used. 268M shared memory used. Anybody know under what conditions X lets go of the 268M? |
