ABSTRACT:
A technique for establishing a dense prefix for a memory in a computer system. Memory is divided into a plurality of chunks. An efficiency factor is generated for each chunk in one or more chunks contained in the plurality of chunks. The efficiency factor may be based on an amount of memory to be reclaimed, an amount of memory to be scanned and an amount of memory to be copied relative to the chunk. A dense prefix is then established for the memory based on an efficiency factor associated with a chunk.
