Memory usage of window managers-need info

Post by Ronald Hayne » Sun, 25 Jul 1999 04:00:00



Hi, I am running SUSE 6.1 on a PII 350 machine
with 196 MB of ram and 128 MB of swap.  I had
previously run SUSE 5.1 on a 486 machine with 28 megs
of ram.  I thought life would be great.  Of course
with a new machine I left my old fvwm2 window manager
in favour of KDE.  The problem is that now after logging
in with KDE running and no application other than
two xterms I have used approx 150 of my 196 megs of ram.
As someone who uses their machine for memory intensive
numerical calculations the remaining 46 megs of ram
just doesn't cut it.

Is this memory usage normal with KDE?  Why so heavy?
It is nice but I am not going to continue to swap out
on even small problems just to have a task bar like
Windows 95.  What other "nice" window managers
exist with the same functionality but less in terms of
system drain.  Any references to memory usage for the
common window managers?

Thanks for the info.
Please respond via email and the newsgroup if possible.

Thanks,
R Haynes

I think you are experiencing the lack of free memory only becuase of the
ironic fact that it is not being used.  In other words, I believe that
the 150MB of ram is really only in the buffer (or cache).  If you were
to actually load up some memory intensive apps and look at top you would
see that the memory would be swapped to those apps and that you would
not be likely to actually run out of memory.

Interesting timing, I have been looking at the various window managers
and the amounts of RAM and CPU share that they demand.  Whatever you do,
if you are concerned about saving resources, do not use gnome with
enlightenment.  This is one of the standard setups for RedHat and
Mandrake's newer 2.2.x kernel distributions.  This combo will drain
memory to the point of crashing X.

Actually, in comparison with Afterstep or FVWM95, on my machine KDE is
actually fairly competitive memory wise.  With any of the mentioned
window managers, top reports about 25MB to X11 alone.  Gnome takes up at
least 35MB on top of that, but one or two windows in KDE adds only
15-20MB.  Afterstep adds 15MB to X.  Of course these are going to be
different for any other machine - but with only 32MB RAM and 64MB swap
KDE does fine on my box.

Try XFwm. I've been using it for about a week now, and it really is more
stable  and easier on resources than other window managers. It looks
great too. It looks a lot like the Solaris desktop. It's available at
http://www.xfce.org
 Hope this helps

I agree completely.  Enlightenment was designed to look nice not to
conserve memory.  Gnome and KDE take up comparable amounts of memory
on my system with nothing else running.  About 15 meg.

One of the most efficient non-fvwm window managers that I've used is
WindowMaker.  According to their web site, one of the objectives of
the WindowMaker project was to keep memory usage to a minimum.  It
only uses 3.5 meg with no open windows and 4 virtual desktops.  The
clip is very functional and works well in place of the Gnome/KDE
"start" bars.

Dunno whether icewm is a non-fvwm window manager, but it's extremely
light on resources:

 12:06am  up 20:41,  2 users,  load average: 0.27, 0.37, 0.40
58 processes: 55 sleeping, 3 running, 0 zombie, 0 stopped
CPU states:  3.8% user,  6.6% system,  0.0% nice, 89.9% idle
Mem:   63032K av,  61728K used,   1304K free,  28780K shrd,   1260K buff
Swap:  64224K av,  16228K used,  47996K free                 19360K cached

  PID USER     PRI  NI  SIZE  RSS SHARE STAT  LIB %CPU %MEM   TIME COMMAND
12298 zlatko     0   0  1056 1056   760 S       0  0.0  1.6   0:04 icewm

That's with one xterm, Free Agent & Notepad under wine, Netscape

free will tell you how much memeory is used in buffers

This looks interesting

I agree whole-heartedly. I have tried all the windowmanagers and found the
best to be WindowMaker. And you'll love the little dockapps that you can get
for WindowMaker. It's a hoot.

I second XFwm, its very light, heres my TOP

  8:54am  up 1 day, 20:27,  8 users,  load average: 0.27, 0.12, 0.03
79 processes: 77 sleeping, 1 running, 1 zombie, 0 stopped
CPU states: 10.0% user,  1.7% system, 11.5% nice, 88.5% idle
Mem:   63448K av,  60932K used,   2516K free,  33532K shrd,   6368K buff
Swap:  51404K av,  20272K used,  31132K free                 16284K cached

  PID USER     PRI  NI  SIZE  RSS SHARE STAT  LIB %CPU %MEM   TIME COMMAND
11380 root      19   0 13108   9M  1004 S       0  8.4 16.1  62:21 X
16657 tp         0   0  6224 6016   904 S       0  0.0  9.4   8:31 tkdesksh
22889 tp         0   0  3656 3656  1952 S       0  0.0  5.7   0:02 xfce

One interesting thing I noticed is the xscreensavers run nearly twice as
fast now ?

Another, is until my son started using Netscape remotely of this box last
night, my swap was a consistant 3.5% for 2 days, whereas under Fvwm2 its
always around 40%.
