Statistics about system attributes. This utility is useful to determine how much paging is in use. If the amount of paging space is less than the amount of real memory in the system, it's possible the system will run out of paging space before real memory. This is because AIX performs early allocation of page space. When a page is referenced, real memory and paging space blocks are allocated. If there are less paging space blocks then real memory pages, paging space will be exhausted before all of real memory is consumed.
