    Make sure that you format ext3 partitions with dir_index which improves
    large directory performance. You'll probably also want to increase the
    number of inodes. Here is what I used:

    mkfs -t ext3 -j -m 1 -O dir_index /dev/sdb1
    tune2fs -c 0 -i 0 /dev/sdb1

    This was on an 800GB Dell/EMC Cx500 array.
