Using Garbage Collection to Implement Cache-Conscious Data Layouts


This talk will discuss a wide variety of techniques for producing
cache-conscious object layouts in languages such as Java and Cecil. These
techniques, which include class/object splitting and object co-location,
leverage the garbage collector and are completely automatic, requiring no
programmer assistance. The techniques are shown to improve the performance of
several medium-sized Java benchmarks by 18-28% overall.
