Andriy Gapon c3d1d2e104 l2arc_write_buffers: reduce headroom value ... FreeBSD has ARC_BUFC_NUMMETADATALISTS metadata lists and ARC_BUFC_NUMDATALISTS data lists (currently both are 16) while illumos has just a single list of each kind. headroom determines how much data is scanned on a single list during each run of the l2arc feed thread. Because FreeBSD has more lists we proportionally decrease the limit. Reviewed by: Brendan Gregg (earlier version) MFC after: 2 weeks Sponsored by: HybridCluster		2014-10-07 16:08:21 +00:00
