    44* '''zfs_resilver_min_time_ms''' /* min millisecs to resilver per txg */
    5 * '''zfs_top_maxinflight = 32; '''          /* maximum I/Os per top-level */
    6 * '''zfs_scan_idle '''                /* idle window in clock ticks */
     5* '''zfs_top_maxinflight = 32; '''          /* maximum I/Os per top-level */ maximum number of scrub I/O per top-level vdev
     6* '''zfs_scrub_delay'''               /* number of ticks to delay scrub */ how many clock ticks to delay scrub operation if triggered by zfs_scan_idle
