More than enough for LCNC, deloptes. Its running on the pi with only a
gig of ram. In a weeks uptime, it has not touched a 10Gb swap. Hasn't
been particularly busy but LCNC has been running, with the machine power
disabled all this time. I have that one rigged to shut off all machine
power when motion is disabled.
