What's wrong with Xubuntu?

Question

linux

Why does naked xubuntu eat so much oz?

Answer 1

Why are we panicking?
She eats normally.
Everything is within the normal range.
I always have Ubuntu 18.04 Unity within the same limits and no problems (but I have a lot of things spinning).

Answer 2

xfce is positioned as a lightweight shell, I would understand another 500-600mb, but 900 is already too much for it.

well, you have somewhere around 600 and it comes out,
683183 K used memory
and those 976MiB are + buffers and caches that accumulate during system operation, for example, caching disk data into memory that the system requests for subsequent quick access.
for clarity, see the command
free -wk
or
free -wh
to reset the excess, you can run the command:

sync; sudo sh -c "/usr/bin/echo 3 > /proc/sys/vm/drop_caches"
