Hi !
I ALWAYS setup swap, whichever RAM size. even with an aggressive swappiness, attempting to maximize RAM use, I see suff in my swap.
Here an exemple with a long session, 3 Firefox profiles with lots of tabs, Gimp, Shortwave & pulseeffect :
[meuh@ordi1 ~]$ free
total utilisé libre partagé tamp/cache disponible
Mem: 11756 4772 3987 574 2996 6099
Partition d'échange: 255 60 195
[meuh@ordi1 ~]$
But, as I don’t know if it’ll be used and what size I should set, I use systemd-swap.
To optimize it, I create a file : /etc/systemd/swap.conf.d/overrides.conf
Where I add to default setup :
swapfc_enabled=1
swapfc_min_count=1
swapfc_chunk_size=512M
In short, it creates a first 512Mo temp swapfile that can be complemented by as many other as needed.
