### Describe your issue

Bonjour,

Afin de soulager la RAM, j’ai étendu la SWAP à 1 Go. Mais bizarrement, il ne semble jamais s’en servir. Même quand la RAM est proche de la saturation, la SWAP reste étrangement vide. Est-ce un comportement normal ?

Bonjour,

Est-ce que le swap est bien activé :

> sudo swapon -a

Est-ce que le swappiness qui est souvent par défaut à 60 n’a pas été mis à 0 (zéro) :

> cat /proc/sys/vm/swappiness

ppr
