This graph gives you an overview of the usage of physical memory in your system. Most operating systems (including Linux) will use as much of the available physical memory as possible as disk cache, to speed up the system performance. This means that if you have a small amount of Free Physical Memory and a large amount of Disk Cache Memory, your system is well configured.
Grafiko honek zure sisteman erabilitako memoria fisikoaren ikuspegi orokorra ematen du. Sistema eragile gehienek (linux barne) erabilgarri dagoen memoria fisiko ahalik eta gehien erabiliko dute baita diskaren cachea ere, sistemaren eraginkortasuna hobetzeko. Honek esan nahi du memoria fisiko libre gutxi baldin baduzu eta diskaren cache memoria kopuru haundia, zure sistema ongi konfiguratuta dagoela.
