Lorsque Linux est utilis\u00e9 en \u00ab\u00a0bureau\u00a0\u00bb (et non pas en serveur) on peut augmenter la rapidit\u00e9 du syst\u00e8me en limitant l’usage de la m\u00e9moire swap au profit de la m\u00e9moire vive beaucoup plus rapide, en r\u00e8glant la valeur de la \u00ab\u00a0swappiness\u00a0\u00bb.<\/p>\n

On peut v\u00e9rifier la valeur actuelle par la commande :
\ncat \/proc\/sys\/vm\/swappiness<\/em>
\nLa valeur par d\u00e9faut est en g\u00e9n\u00e9ral de 60
\nPour changer cette valeur \u00e0 chaud on emploie la commande :
\nsysctl -w vm.swappiness=10<\/em>
\nPour rendre le changement permanent il faut \u00e9diter le fichier \u00ab\u00a0\/etc\/sysctl.conf\u00a0\u00bb et rajouter la ligne :
