摘要
Mechanisms are provided for data placement optimization during runtime of a computer program. The mechanisms detect cache misses in a cache of the data processing system and collect cache miss information for objects of the computer program. Data context information is generated for an object in an object access sequence of the computer program. The data context information identifies one or more additional objects accessed as part of the object access sequence in association with the object. The cache miss information is correlated with the data context information of the object. Data placement optimization is performed on the object, in the object access sequence, with which the cache miss information is associated. The data placement optimization places connected objects in the object access sequence in close proximity to each other in a memory structure of the data processing system.
