Abstract
Applications written in modern garbage collected languages like C# tend to have large dynamic working sets and poor data locality and are therefore likely to spend excess time on managing data movements between memory hierarchies. Instead, a low overhead dynamic technology improves data locality of applications. The technology monitors objects while the program runs and places recently accessed objects on the same page(s) on the heap. Providing increased page density is an effective method for reducing DTLB and/or data cache misses.
