Not that rare. My desktop machine has 8 GiB of ram, and swap usage yesterday was around 2.5 GB. But I wouldn't ever do a swapoff, except when moving to another disk or something maintenance wise.
I guess if you use VMs or other high memory applications (video photo editing?)
Maybe what happens is not that a block is moved from one swap to another, but that some memory blocks are swapped out again to the available spaces, thus freeing memory for the process that is doing the swap off.
I guess.
But it is not a continuous read. Much processing has to be done for each block, apparently.
Apparently that is a repeated searching of trees ;-). Or maps. Or lists.
It's not pleasant and it's not beautiful. And if it hinders shutdown I can expect it to be an issue.
But it doesn't seem to be so.
And so we all wonder what the need is. Although it would be a nice project perhaps. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
