Abstract:
In an embodiment, a plurality of stack depths of a stack are sampled from all stack depths of the stack. An average of the plurality of stack depths is calculated. If a number of the plurality of stack depths is greater than a maximum sample threshold and the average of the plurality of stack depths is greater than or equal to a current depth of the stack, then pages are deallocated from the stack that are above the average of the plurality of stack depths. If the number of the plurality of stack depths is greater than the maximum sample threshold and the average of the plurality of stack depths is less than the current depth of the stack, then pages are deallocated from the stack that are above the current depth of the stack.
