Can the swap-block locater be made >adaptive, or does it rely on a uniform (and static) m/n distribution? It's a function of the way that the interleaved allocation works. So the answer is no, it does not change as a function of the drive-load. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
