For HDD based pools the default zfs_scan_vdev_limit of 4M per-vdev can significantly limit the maximum scrub performance. Increasing the default to 16M can double the scrub speed from 80 MB/s per disk to 160 MB/s per disk. This does increase the memory footprint during scrub/resilver but given the performance win this is a reasonable trade off. Memory usage is capped at 1/4 of arc_c_max. Note that number of outstanding I/Os has not changed and is still limited by zfs_vdev_scrub_max_active.
