Modeling memory compression

A computer usable program product comprising a computer usable storage medium including computer usable code for modeling memory compression, the computer usable code comprising:

• computer usable code for receiving a subset of candidate pages from a set of candidate pages used in executing a workload in a data processing system, a candidate page being compressible uncompressed data in a memory associated with the data processing system;
• computer usable code for compressing the subset of candidate pages in a scratch space;
• computer usable code for computing a compressibility of the workload based on the compression of the subset of candidate pages;
• computer usable code for receiving page reference information of the subset of candidate pages;
• computer usable code for determining a memory reference rate of the workload;
• and
• computer usable code for presenting a recommendation about a memory compression model for the workload in the data processing system.

A data processing system for modeling memory compression, the data processing system comprising:

• a storage device including a storage medium, wherein the storage device stores computer usable program code;
• and
• a processor, wherein the processor executes the computer usable program code, and wherein the computer usable program code comprises:
