gnome-system-monitor and memory

[mdg583]

Hello,
I was wondering if the gnome-system-monitor is working with regard to memory history? I run 7.1-PRERELEASE 7.1-PRERELEASE, and have gnome-system-monitor-2.22.4. It pretty consistently shows about 148mb of memory. It goes up and down, but not as much as I'd expect.
For instance, I just opened openoffice, and it went from 140 mb to 170 mb. But 'top' tells me soffice.bin is has 124M SIZE and 93416 RES:

CPU: 92.9% user, 0.0% nice, 6.8% system, 0.4% interrupt, 0.0% idle
Mem: 277M Active, 1030M Inact, 175M Wired, 3568K Cache, 112M Buf, 509M Free
Swap: 4063M Total, 4063M Free

PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND
58889 matt 6 44 0 124M 93416K select 0:00 0.00% soffice.bin
54945 matt 6 44 0 115M 91644K ucond 0:13 0.00% firefox-bin

Those two alone should be using more than 170 mb.

This isn't a critical problem, obviously. I was just wondering if this could work better.
Also, both 'top' and gnome-system-monitor show that none of my swap space is being used. "Swap: 4063M Total, 4063M Free". Is this okay?

Yes it could. Open the shell and type

$top

Sorry, I forgot to say that there is special utility for checking swap. On
OpenBSD is swapctl


$ swapctl -l
Device 512-blocks Used Avail Capacity Priority
swap_device 1058400 0 1058400 0% 0

yes, i view some of you - top say, that memory active 50%, but GSM - 25%...
by the way - swap usage view thas same top and GSM

[richardpl]

How you counted that top says 50% ?

[arachnid]

How you counted that top says 50% ?
only active memory

DESCRIPTION OF MEMORY
Mem: 9220K Active, 1032K Inact, 3284K Wired, 1MB Cache, 2M Buf, 1320K
Free Swap: 91M Total, 79M Free, 13% Inuse, 80K In, 104 K Out

K: Kilobyte

M: Megabyte

%: 1/100

Active:
number of pages active

Inact: number of pages inactive

Wired: number of pages wired down, including cached file data pages

Cache: number of clean pages caching data that are available for imme-
diate reallocation

Buf: number of pages used for BIO-level disk caching

Free: number of pages free

Total: total available swap usage

Free: total free swap usage

Inuse: swap usage

In: pages paged in from swap devices (last interval)

Out: pages paged out to swap devices (last interval)


swapinfo(8) is general tool for monitoring swap usage. General rule apply: less used swap - better for your system interactivity and disk life.

Not necessarily. They are both linked to many of the same libraries, which don't need to have a new copy loaded each time they are mapped into a different process space.

I suspect it's fine the way it is.
