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
Filename				Type		Size	Used	Priority
/dev/zram0                             	partition	524284	0	100
/dev/zram1                             	partition	524284	0	100
/dev/zram2                             	partition	524284	0	100
/dev/zram3                             	partition	524284	0	100


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
