Is the KDE/Plasma "System Load" calculation of application used memory
correct ?

Currently on my system the KDE "System Load" panel widget shows 11.3G of
memory used by applications in a 24G memory system. ksysguard is the same.

/proc/meminfo shows:

MemTotal:       24689476 kB
MemFree:         1081276 kB
MemAvailable:   20106752 kB
Buffers:         4722180 kB
Cached:          7071252 kB
SwapCached:         4156 kB
Active:          8374976 kB
Inactive:        6882576 kB
Active(anon):    2623148 kB
Inactive(anon):  1005372 kB
Active(file):    5751828 kB
Inactive(file):  5877204 kB
Unevictable:          32 kB
Mlocked:              32 kB

The "top" program states 4G used which matches the /proc/meminfo. So the
11G seems incorrect...

guess what the 4 GB + cached gives....

hence the systemload widget splits the memory in different colors to distinct between cache and resident memory used by applications

cached is also memory  and it's used so nothing wrong besides that "how much memory i am using" is a terrible complex question with a ton of different answers

Sorry that doesn't make sense. If the SystemLoad widget shows Application usage as "Application + cache" then it is not distinguishing between cache and resident memory used by applications ...

I would have thought that it should show separately: "Application, cache, buffers" rather than: "Application + cache, cache, buffers".
