Abstract

A method, information processing system, and computer readable medium for efficiently distributing a computer system's main memory among applications running in that operating system instance. More specifically, threshold values used by a page replacement algorithm of the virtual memory manager are automatically tuned in response to the load on the memory of a computer system. One such threshold value is the lower threshold of free memory which is changed as a function of the load on the memory. For example, such a load might be represented as the number of threads that were added to a waiting queue during a defined interval of time divided by the number of clock tics in that interval (202). This representation is known as the thread wait rate (203). This rate is then compared to a target rate to determine if the lower threshold value should be changed (204). When the free memory space falls below the lower threshold, a page replacement daemon is used to page out memory to make more memory space available (201).
