Abstract: Embodiments of the present invention provide a memory resource optimization method and apparatus, relate to the computer field, solve a problem that existing multi-level memory resources affect each other, and optimize an existing single partitioning mechanism. A specific solution is: obtaining performance data of each program in a working set by using a page coloring technology, obtaining a category of each program in light of a memory access frequency, selecting, according to the category of each program, a page coloring-based partitioning policy corresponding to the working set, and writing the page coloring-based partitioning policy to an operating system kernel, to complete corresponding page coloring-based partitioning processing. The present invention is used to eliminate or reduce mutual interference of processes or threads on a memory resource in light of a feature of the working set, thereby improving overall performance of a computer.
