avg 2010-09-17 07:14:07 UTC FreeBSD src repository Modified files: sys/cddl/contrib/opensolaris/uts/common/fs/zfs arc.c Log: SVN rev 212780 on 2010-09-17 07:14:07Z by avg zfs arc_reclaim_needed: more reasonable threshold for available pages vm_paging_target() is not a trigger of any kind for pageademon, but rather a "soft" target for it when it's already triggered. Thus, trying to keep 2048 pages above that level at the expense of ARC was simply driving ARC size into the ground even with normal memory loads. Instead, use a threshold at which a pagedaemon scan is triggered, so that ARC reclaiming helps with pagedaemon's task, but the latter still recycles active and inactive pages. PR: kern/146410, kern/138790 MFC after: 3 weeks Revision Changes Path 1.44 +3 -3 src/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/arc.c
