The 30% rule is a performance rule, not a capacity rule: 1. you should have enough space to accommodate a large page-out burst, when I occurs. 2. you should not fill this space over 30% to keep good performance on your page-outs. Although I think this rule is more important in a constantly paging system and less important for a one time page-out burst.

As long as he doesn't exceed 30% usage, he should be fine. Maybe automatically issue the command hourly to find the peak?
