- Allow reuse of unused sections that fit exactly to selected allocation size. Decreases fragmentation dramatically. - Always allocate and align mapped memory to selected alignment. Avoids having fragmented unused maps that are not aligned. - Use a static alignment based on BPMP and generally average cache line size. Boosts performance when MMU is used.
