I no longer see any usewhat do you say ?
It is difficult to provide general advice. On FreeBSD-based appliances, such as embedded routers or NAS devices, it is quite common to see swap disabled. Such systems may not have any disks suitable for swapping[4], or their designers may not have been willing to accept potential application latency caused by faults on paged-out memory. In versions of FreeBSD before 11.0, the page daemon was responsible both for freeing clean inactive pages and laundering dirty inactive pages, so large amounts of paging activity could delay reclamation of memory and trigger freezes.
