Swappiness centos server guide -369-

(17 replies) Hi all, This might not be CentOS related at all. Sorry about that. I have lots of C6 & C7 machines in use and all of them have the default swappiness of 60.

However, some still swap even if they have lots of Swap space is an area of disk that is used to store memory to.
