Hi @ai,

Calculating the RAM usage is not trivial as Linux kernel accounting does not provide a single value as "used RAM", but usage is split across categories. You can see how Linux tracks memory allocation by running cat /proc/meminfo. The extension implemented the same formula for calculating RAM usage as the htop application which looks like this:

Gnome's System Monitor must use a different formula I suppose.

I don't have information about which calculation method is the correct/official.
