Just a stupid wondering:
How come that Mate, that is supposedly extremely lightweight (well maybe not by design but by origin) has so many apps that are heavier than other DE:s?
I mean not everything can be revealed by looking at numbers, but for example Mate’s system manager uses, according to plain numbers, three times as much memory as Gnome’s system manager. Mate’s calculator uses three times as much memory as Galculator. And so on.
My only guess is that other DE:s has more services already running, so the actual memory cost of the application is “hidden” by some of what it is needing always is running anyway (a specific example from across the tracks is IE, that on paper was very lightweight but that’s because 80% of it was in fact always running as part of Windows, started or not started).
