How to properly tune zswap with MGLRU?

Optimised KDE 6: baloo is disabled, Akonadi & other KDE PIM are uninstalled.

It turns out Plasma System Monitor consumes 200 MB, but KSysGuard is not available for Leap 16.0: Optimising KDE - alternatives for Plasma System Monitor?

I’m trying htop.

I tried IceWM, but it is not suitable for me using tablet PC.

256 MiB was too much for VRAM, now I use 128 MiB. Lowering to 64 - 96 MiB VRAM - is it suitable?
