[plasmashell] [Bug 369566] Absurdly high memory usage from kwin_x11, plasmashell, krunner, and kded5

--- Comment #6 from Mathieu Jobin  ---
I agree with David, this is not a valid measure of process memory usage.

not only its irrelevent to consider the total size to swap a process we use
constantly

but also, I see processes showing up at the top of that list that i know for
sure has no impact on my machine whether I bring them up, or close them
like kate and kmail which shows 4th and 1st respectively. kwin is 2nd and
plasmashell 3rd.

I can kill plasmashell it will make no performance impact on my system, I can
relauch plasmashell it will have again no impact on my system.

sorting by rss is much more accurate in my opinion

here is my top 15

[mathieu@hz550 ~]$ ps -eo rss,command | sort -nr | awk {'print $2'} | head -n
15
kwin_x11
/opt/google/chrome/chrome
/usr/bin/qupzilla
/usr/bin/kmail
/opt/google/chrome/chrome
/opt/google/chrome/chrome
/opt/google/chrome/chrome
/usr/bin/plasmashell

/usr/lib/jvm/default-runtime/bin/java

/usr/lib/xorg-server/Xorg
/opt/google/chrome/chrome
/opt/google/chrome/chrome
/usr/lib/qt/libexec/QtWebEngineProcess
[mathieu@hz550 ~]$ 

even if kwin shows first, i don't care as i need it 100% if the time and its a
single process.

32 chrome process is much more of a problem in my life

 mathieu@hz550 ~]$ ps -eo rss,command | sort -nr | awk {'print $2'} | grep
chrome | wc -l

[plasmashell] [Bug 369566] Absurdly high memory usage from kwin_x11, plasmashell, krunner, and kded5

[Luke-Jr via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=369566

--- Comment #5 from Luke-Jr  ---
SIZE measures the amount of swap space a process would use if it were swapped
out entirely. So while this might include some shared memory, it would only
include it once per process, which isn't unreasonable for this report. It would
also not include mmapd pages unless they were anonymous mmaps not stored on
disk or used to access some other hardware, which are really no different than
mallocs and therefore should be included in every meaningful measurement.

If you'd prefer I use another measurement, which do you suggest? The other
alternatives all appear to be much less valid.

That's not a valid measure. 
You're including shared memory multiple times as well as mmapd data pages.

ps -eo size,pid,args | sort -n

AFAIK this is the only reliable way when swap is in use...?

hmm, that strange, I have 3.8GB of ram on my ultrabook

kwin_x11 takes 188MB
plasma 92MB
krunner 22MB
kded5 takes 2360KB

and i'll throw Xorg in there as well, as it is quite critical
44MB

Chrome and Firefox are the two biggest memory consumer... 

I have mysqld, postgresql, elasticsearch and several other backend services...
only firefox and chrome together brings my tiny system to a crawl

for that reason, I use qupzilla (169MB) 7 tabs open at the moment

How are you determining memory usage?
