Some diskless workstations use NFS as swap space. Why is this approach useful? What is the downside?
What will be an ideal response?
Because it has no disk space, a diskless workstation has no swap space. The
only choice is to use NFS; if it did not use NFS for swap space, the work-
station would be limited by the amount of its physical memory (RAM).
Swapping in general is slow because disks are much slower than RAM. NFS
is even slower than a local disk; any process that uses an NFS swap space
will spend a long time waiting for pages to be swapped in.
