I'd reword Andy's "a system with a significant amount of memory" to
something like "unless the system is seriously RAM constrained".
$ free -m
total used free shared buff/cache available
Mem: 3938 1481 984 277 1472 2150
Swap: 2047 0 2047
$ /sbin/swapon -s

This is an ARM64 laptop running LXDE with two instances of
xfce4-terminal each with its own tmux (one of them running two instances
of neomutt), plus Firefox with lots of tabs (admittedly most of them
inactive -- 20 or so active tabs is the usability limit) everything
running from a 32GB USB stick.
The electricity consumption is probably minimal, so I never bothered
with hibernating, I only let lightdm turn of the screen when it's not in
use.
Kind regards,
Andrei
