With small memory it is worthwhile severely restricting the ARC allocation for ZFS by setting vfs.zfs.arc_max to match vfs.zfs.arc_min (I'm not sure if you can reduce both safely - worth experimenting). Ny default ZFS is configured too greedy to run much else unless you have a lot of memory. -- Steve O'Hara-Smith <steve@sohara.org>
