Hi!

I'm testing openSUSE Leap with Plasma 5 in a VirtualBox-VM (1 CPU / dual-monitor-setup).

With only 4 windows open (kwrite/Dolphin/System Settings/ksysguard) "plasmashell" consumes roughly 190.000 K and CPU-load is between 3 and 4 %.

In an otherwise identical VM with oS 13.1 and Plasma 4 the values are 100.000 K and 0 %.

Can anyone confirm higher memory-/CPU-usage for Plasma 5 compared to Plasma 4? Or could they be due to Leap?

Regards!

"plasmashell", the process or the entire session?
In case of the session, see whether you can pin a process (kwin will easily "consume" memory if the compositor is active and textures and FBOs are stored client side by the VM driver)

The process (as seen in "Systemmonitor").

"plasmashell" and "X" are always active (X between 1 and 2 %; plasmashell right now 2-3 %). In Plasma 4 "plasma-desktop" and "Xorg" are at 0 % (CPU).
In Plasma 5 "plasmashell" consumes 150.000 K with 4 windows open, "plasma-desktop" 116.000 K with lots (!) of windows open. All according to ksysguard.

The amount of opened windows should really not have impact on the memory demand of plasmashell.
The difference *might* stem from the memory assignment (notably if you were using the native graphicssystem in KDE4, much visual data that's now in OpenGL would have been on the X11 server)

Also compare the ouput of "cat /proc/meminfo", I'm not gonna swear around, but all other memory representation tools are rather useless...
