3 Windows showing different system monitors, on the bottom left is top, on the top left its htop and the right its plasma-systemmonitor

plasma-systemmonitor shows an exaggerated ram usage after using the system for a while


1.  Start Plasma6
2.  Use the system normally or idly 
3.  Measure high ram usage despite 2.

OBSERVED RESULT

The system monitor is reporting a false number that shows the ram usage climbing as system is being used, this is the same number reported by top but not reported by htop/btop

EXPECTED RESULT

It should show a realistic number going in line with system monitors like htop/btop and not an exaggerated number

It actually turns out that there are many ways to measure memory usage, because there are many different types of memory. This means that memory usage measurements between different apps and CLI tools are always bound to differ based on what their authors count as memory, unfortunately.
