Abstract
A method for managing a computer system process memory allocated to execution of a process configured to use data stored to storage is provided. The process memory has a predetermined size and is filled by uncompressed pages of data necessary to execute the process being copied from the storage. The process memory is partitioned into an uncompressed region having an adjustable first size and a compressed region having an adjustable second size. The uncompressed region includes uncompressed pages of data and the compressed region includes compressed pages of data. The first size of the uncompressed region and the second size of the compressed region are adjusted when a requested page of data necessary for continuing the execution of the process resides in either the storage or the compressed region.
