Abstract
Profiling cache replacement is a technique for managing data migration between a main memory and a cache memory to improve overall system performance. A profiler maintains counters that count memory requests for access to the pages maintained in both the cache memory and the main memory. Based on this access-request count information, a mover moves pages between the main and cache memories. For example, the mover can swap little-requested pages of the cache memory with highly-requested pages of the main memory. The mover can do so, for instance, when the counters indicate that the number of page access requests for highly-requested pages of the main memory is greater than the number of page access requests for little-requested pages of the cache memory. To avoid impeding the operations of memory users, the mover can perform page swapping in the background at predetermined time intervals, such as once every microsecond (μs).
