Disabilitare tutti i filesystem in ram
Buongiorno lista,
Ho un problema di consumo di ram sul portatile, in particolare non
riesco in nessun modo ad azzerare la voce buff/cache che ha sempre
600/900MB occupati. Ho provato con "echo 3 > /proc/sys/vm/drop_caches"
ma nulla, durante il normale utilizzo piuttosto mi si riempie la swap,
ma Linux non libera la RAM. Credo che il motivo sia che ho dei file
systems in RAM, ma con systemd non so come verificarlo o disabilitarlo.
Sapete aiutarmi?
questo è l'output di cat /proc/mounts:
