Memroy invasion

[Patrick Dupre]

Hello,

Running only firefox, htop indicates: an occupation of 14.6 of the 
memory and of 11.5% for gnome-shell (actually 1.4 G/ 3G of RAM).
This slows down the machine without clear explanation.
Actually, it becomes a lot worst as soon as I run xmgrace for example.
I run fc21
Of course, if I kill firefox, the memory occupation is gone, but I
still keep the 11.5% of gnome-shell while only one gnome-terminal is open.
(I do not run ant thing, only the OS runs some stuff).
