Method, system and computer program product for using an instantaneous memory deficit metric to detect and reduce excess paging operations in a computer system

摘要

A method, system and computer program product for detecting when insufficient RAM is available in a computer system, and estimating the additional RAM needed to avoid excess paging. The invention uses memory management parameters to estimate the number of frequently-used pages stored in "virtual memory" on disk. If this estimate is nonzero for an appreciable period the amount of RAM is insufficient, and RAM equal to the estimate should be added to the system.
