(which is a darn good reason not to move /tmp to being RAM based, as it gets used for large files sometimes, and .. oops. there goes your memory!...;-)
Or NOT as the case may be. First, a tmpfs is mapped to memory in a way that slightly more efficient than a disk based FS. Yes, disk based FSs are mapped to memory, buffers, for reading writing inodes and super-blocks as well as shuffling the B-trees and indexes and more. By comparison a tmps is incredibly light weight. Secondly, Linux uses a demand paged virtual memory so you're never going to run out of memory, for whatever value of 'never' applies. And it does apply here. If that memory is needed by a process it can be paged out to swap. -----Original Message----- It makes me wonder if you ever used k3b or kiwi.... Or are you blessed with 32GB unused mem or more at home? Swap? Some systems don't use swap, as it is a perfect way of destroying ssd. (or do you use your mem as swap device ;-) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
