Here is the RAM usage on my 11 day uptime F14 laptop
$ sudo ps_mem.py¹
Private + Shared = RAM used Program
1.9 MiB + 252.5 KiB = 2.1 MiB NetworkManager [updated]
7.0 MiB + 1.6 MiB = 8.6 MiB nm-applet [updated]
I notice both were updated so restarting gives:
$ sudo ps_mem.py
1.4 MiB + 290.0 KiB = 1.7 MiB NetworkManager
2.6 MiB + 1.3 MiB = 3.9 MiB nm-applet
