Pawel Jakub Dawidek 2d03e33170 Try to stabilize ZFS with regard to memory consumption: ... - Allow to shrink ARC down to 16MB (instead of 64MB). - Set arc_max to 1/2 of kmem_map by default. - Start freeing things earlier when low memory situation is detected. - Serialize execution of arc_lowmem(). I decided to setup minimum ZFS memory requirements to 512MB of RAM and 256MB of kmem_map size. If there is less RAM or kmem_map, a warning will be printed. World is cruel, be no better. In other words: modern file system requires modern hardware:) From ZFS administration guide: "Currently the minimum amount of memory recommended to install a Solaris system is 512 Mbytes. However, for good ZFS performance, at least one Gbyte or more of memory is recommended."		2007-04-10 02:35:57 +00:00
