Abstract
A method, computer program product, and system are provided for prefetching data into a cache memory. As a program is executed an object identifier is obtained of a first object of the program. A lookup operation is performed on a data structure to determine if the object identifier is present in the data structure. Responsive to the object identifier being present in the data structure, a referenced object identifier is retrieved that is referenced by the object identifier. Then, the data associated with the referenced object identifier is prefetched from main memory into the cache memory.
