Eric van Gyzen 73511c241b Set zfs_arc_meta_strategy to metadata only ... The previous default of "balanced" appears to have caused pathological behavior, including very poor performance and 100% CPU load in the arc_reclaim_thread. The symptoms appeared when the daily periodic run started. With this change, the system--and the ARC in particular--behaved normally during a manual daily periodic run. From Mark Johnston: The port of the balanced strategy is incomplete, since arc_prune_async() is a no-op on FreeBSD. (This also seems to imply that r337653 is a no-op.) After 12 is branched we can port the remaining bits and consider changing the default back.
