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. L2ARC_WRITE_SIZE determines the default value of l2arc_write_max which defines limits on how much data is scanned and written to a cache device during each run of the l2arc feed thread. The limits are applied on the per buffer list basis. Because FreeBSD has more lists we proportionally reduce the limits.
