I see at least 5.2MB of physical RAM for data to supervise a single WiFi connection. That's too much. Another 400KB is for bluetooth kernel module. I can't prove that bluetooth is not present (lspci omits any mention), but I'm definitely not using it (keyboard, mouse, sound are all direct wired.) Modem-manager is active even though I'll never use it. $ ps alx F UID PID PPID PRI NI VSZ RSS WCHAN STAT TTY TIME COMMAND 4 0 614 1 20 0 523576 11672 poll_s Ssl ? 0:01 /usr/sbin/NetworkManager --no-daemon $ cat /proc/614/smaps 02405000-024c2000 rw-p 00000000 00:00 0 [heap] Private_Dirty: 648 kB Referenced: 648 kB Anonymous: 648 kB 7ff50f800000-7ff510000000 rw-p 00000000 00:00 0 Private_Dirty: 2048 kB Referenced: 2048 kB Anonymous: 2048 kB AnonHugePages: 2048 kB 7ff51fc01000-7ff520401000 rw-p 00000000 00:00 0 [stack:627] Private_Dirty: 2052 kB Referenced: 2052 kB Anonymous: 2052 kB AnonHugePages: 2048 kB $ dmesg Apr 25 05:56:36 localhost NetworkManager[614]: <info> modem-manager is now available Apr 25 05:56:36 localhost dbus-daemon[501]: modem-manager[641]: <info> ModemManager (version 0.6.0.0-3.fc19) starting...
